A funny story about three handshakes and four waves: How to seize the opportunity when you meet a girl you like?

I have a friend, Xiao Long, who confided in me:

He was chatting with a friend in a cafe and met a girl who made time stand still. He described that at that moment, his heart was completely captured, his mind was buzzing, and he could not take his eyes away from her. And the girl would look at him from time to time, with a pair of clear eyes like autumn water.

Xiao Long said that he really wanted to seize the opportunity and was moved this time. However, from beginning to end, he failed to take that step and he didn't know what to do.

TCP protocol handshake: How to start an emotional bond.

Xiao Taki's dilemma is the dilemma of every boy.

I told him that if you understand the TCP protocol, you will understand a relationship.

TCP (Transmission control protocol) is not only the basic protocol for transmitting information between machines, but also the principle for people to communicate with each other.

How to get to know her decently? How to understand whether she likes you? How to give her a sense of security? How to get her mobile phone number when leaving? The TCP protocol writes everything clearly.

First Handshake

I said to Xiaotaki:

A girl, no matter how cold her personality is, will always be happy to accept your affection.

What you have to do, and must do, is:

I told Xiao Long that I once met a girl at the airport who instantly made my heart flutter. All I did was walk up to her naturally and tell her:

"You seem to be on this flight as well? The flight number is KN5855, right?"

This is very easy for boys, because the place you appear in is a resonance. You must have some specific information to share about this place.

So, Xiaotaki, you should go up and say:

You must come to this cafe often, their caramel macchiato is really great.

Such conversations provide girls with a sense of security:

You are a man who has common topics and provides substantial value, not just someone who is just trying to hook up. The power of resonance is very strong, and no girl will refuse to respond, even if she looks a little shabby.

Back to the TCP protocol, it is stipulated as follows:

(SYN is the abbreviation of synchronization, and seq is the abbreviation of sequence number.)

At this time, the client's status changes to SYN-SENT (synchronization_sent). In other words, Xiao Taki, you just need to wait patiently for the girl to respond.

This is the "first handshake".

Second handshake

With the synchronization request SYN=1 and the specific information seq=x you provided, the girl will respond according to this information. The girl's state at this time changes from LISTEN to SYNCRCVD (synchronizationrecieved synchronization received).

This is what the girl I met at the airport said to me:

Yes, I'm on this flight too, but I didn't see you. Are you on a business trip to Shenzhen?

It is human nature to answer like this, and you will definitely get a warm and friendly response.

The TCP protocol stipulates that:

(ACK is the abbreviation of acknowledgment, and the lowercase ack is the confirmation number)

Therefore, the girl will definitely agree with you, expand on the previous information point, and provide a new information point.

The girl is not disgusted by you, but she also needs to confirm whether you really like her.

What if I really just think the flight number is auspicious? What if you, Xiao Long, really like to drink caramel macchiato? She can't be sure whether the boy wants to communicate with her, so she must bring up new topics. Moreover, bringing up new topics will make both parties feel less awkward.

The girl will almost certainly respond with something like:

So Xiao Long, the girl you like will almost certainly respond in a similar way:

Mmm, I like hazelnut macchiato. I live nearby, how about you?

When you receive such a friendly response, you will know that you can at least establish a preliminary friendship. At this time, your status changes to ESTABLISHED. (Established connection)

The third handshake

Although for you, this young friendship between men and women has been established. But the girl is still waiting for your response - she is also worried that you are just asking casually.

Hurry up and comfort this kind and beautiful girl!

For example, I would answer:

Yes, there are a few clients in Shenzhen who need to talk. I was in business class so I didn't see you.

So, Xiao Long, you need to respond to her new topic and don't lose your own topic. In this way, both topics can be discussed.

The TCP protocol stipulates that:

This is very important for a girl. You agree with what she says and can pick up her topic without losing your own topic. You are someone who can take care of her feelings and stick to yourself.

At this point, the girl's status becomes ESTABLISHED. You both have become ESTABLISHED, and then you can communicate unimpeded.

TCP's three-way handshake is also the most optimized love game.

Boys will think, how can I appear reliable? TCP gives the answer: resonance + specific topics.

The girl will think: Is he interested in me? Is he someone I can talk to? How to conduct a "shit test"? TCP gives the answer: resonance + agreement + extension of the other party's topic + new specific topic.

The boy would think, how can he leave her with a good impression of being independent-minded and having high emotional intelligence? TCP gave the answer: agree + extend the other party's topic + continue your own topic.

If you think about it carefully, this method makes both parties feel neither embarrassed nor embarrassed, and it also saves both people's time and energy.

TCP protocol waving: how to say goodbye gracefully.

Time is always short. You have had a great time talking to each other, but now it is time to say goodbye.

Only a decent farewell means that the relationship can continue to warm up in the future.

Don't worry, the TCP protocol has been planned for you.

1. First wave

As the male who takes the initiative, you need to express your separation first. Don't drag it out and wait until the girl brings it up. This way, you can leave behind a sense of aftertaste and reluctance for this encounter.

you need to

Now is the best time to ask for your mobile phone number/WeChat ID.

The TCP protocol stipulates that:

(FIN means finis)

You have finished your request, just wait quietly. Take the initiative and be silent, give the girl enough space, this is the most decent way to say goodbye. At this time, your status is FIN-WAIT-1 (Termination Waiting 1)

2. Second wave

The passionate chat suddenly came to an abrupt end. The girl will feel a little disappointed. At this time, she will almost certainly agree to your WeChat request.

At this time, the girl will find a piece of paper, write her mobile phone number or WeChat number to you, and say something else to you.

For example, she said:

Yes, wait for me to write it to you. You see, it looks like it's going to rain soon.

The TCP protocol stipulates that:

Because you are the one who suggested leaving, the girl is still reluctant to leave. On the one hand, she will agree to leave, and on the other hand, she will extend your topic. In order to confirm that you really want to leave, she will usually bring up a new topic, such as it's raining.

From the time a girl receives your request to leave until she responds to this sentence, she is in CLOSE_WAIT state. She will begin to prepare herself mentally and adapt to the feeling of emptiness when you leave.

Of course, adults always express themselves in a subtle and respectful way. It was just a simple "It's going to rain soon".

You hear her say this, but you remain silent. You enter the FIN-WAIT-2 state.

You are waiting for her cell phone number, but maybe she suddenly stops writing to you? Hold back and don't respond.

3. The third wave

When the girl lowered her head and wrote down her phone number, she was ready to leave, knowing that this encounter was over. At this time, she said:

Come back soon, I'll write to you. I don't know why it's so pleasant to be with you.

Look, the TCP protocol affects your behavior patterns. If you don't respond, she will change the subject, she will start to guess, she will start to wait, she will start to linger.

The TCP protocol stipulates that:

The girl who said this entered the LAST_ACK (final action) state - the initiative is in your hands and she is waiting for you.

You hear the girl talking again, you feel reluctant, you are waiting for something. You enter the TIME_WAIT stage.

4. The fourth wave

Knowing that she is leaving, your heart will suddenly ache. But leaving is inevitable, so say your last words to her decently!

The TCP protocol stipulates that:

After hearing what you said, the girl closed the car door and the car started slowly. The girl entered the state CLOSED.

You proposed to leave, but you stood there for a long time. After waiting for 2MSL (the time it takes to respond to two conversations), you hoped that the car would suddenly stop and the girl would get out of the car.

But nothing happened.

The wonderful encounter is over. You enter the CLOSED state.

TO：Otaki

Xiaotaki, do you know?

If you understand the TCP protocol, you will know how to catch the girl who touches your heart.

Perhaps, this is what a chance encounter should look like:

(1) "You must come to this cafe often. Their caramel macchiato is really good."

• SYN=1, seq=x
• The client enters the SYN_SENT state.

(2) "Me too. I like hazelnut macchiato. I live nearby. How about you?"

• SYN=1, ACK=1, ack=x+1, seq=y
• The server was originally in the LISTEN state. After sending, it entered the SYN_RCVD state

(3) "What a coincidence! I live nearby too. Their macchiato is their signature drink."

• ACK=1,ack=y+1, seq=x+1
• After sending, the client transitions from the SYN_SENT state to the ESTABLISED state.
• After receiving the packet, the server enters the ESTABLISTED state from the SYN_RCVD state.

When you leave, you will be reluctant to leave like this:

(4) "I have something else to do. Please add me on WeChat!"

• FIN=1, seq=u
• The client enters the FIN-WAIT-1 state from the ESTABLISED state.

(5) "Okay, I'll send it to you~ Haha, your profile picture is so cute"

• ACK=1, ack=u+1, seq=v
• After sending, the server enters the CLOSE-WAIT state from the ESTABLISHED state.
• After receiving the message, the client enters the FIN-WAIT-2 state from the FIN-WAIT-1 state.

(6) "Go do your thing! I've sent it. I'm having a great time today!"

• FIN=1, ACK=1, ack=u+1, seq=w
• After sending, the server enters the LAST_ACK state from the CLOSE-WAIT state.

(7) "Ah, got it. I'm glad to meet you, too."

• ACK=1, ack=w+1, seq=u+1
• After sending, the client enters the TIME-WAIT state from the FIN-WAIT-2 state.
• After receiving it, the server enters the CLOSED state from the LAST-ACK state.

Then, she left. You stared at her, turning back again and again until she disappeared from your sight.

• After waiting for 2MSL, the client enters the CLOSED state from the TIME-WAIT state.

Every day, trillions of TCP connections are replaying this scene for you.

Be brave and don't worry about being rejected. Trillions of TCP connections have succeeded, so how can you fail?

Because TCP is the rule of network communication and also the tacit communication rule among humans.

Without showing any emotion, my heart is already surging. But I am only saying this to you.

"What a coincidence, I'm on this flight too."

[[272670]]

A few rules to help you remember all this:

• Every communication carries a seq sequence code, and every communication changes the state.
• SYN=1 is sent once by both parties during the handshake phase. FIN=1 is sent once by both parties during the wave phase.
• When there is a confirmation code, ACK=1, which must be accompanied by a confirmation number ack. ack is the sequence number of the previous one received + 1.
