Strangers Interaction

There are some characteristics of strangers-interaction:

1. consist of communication between two or more people
2. run in short period of time;
3. happen in public places, e.g: train, shops, street, etc.
4. based on mutual-short-term physical circumstances, e.g: strangers being passengers of a train because of a mutual interest of going to their destinations, strangers being in a bus stop because of a mutual interest of waiting for a bus to come.

Recently, I took a train from Malang and Semarang, and interacted with two strangers during the trip. We were perfectly fulfilled those characteristics and we had such a great trip because of each other. Once I arrived in Semarang, one of those two strangers, tried to extend our strangers interaction which ignores characteristic number two, three and four. Let's called him X.    

What did he do? 

After I arrived in Semarang, according to the characteristics, the strangers-interaction between me and those two strangers, are automatically ended. Because the short period of time has ended (characteristic number 2) and I didn't have the mutual-short-term physical circumstance with them anymore (characteristic number 4).

But instead, X was keep on sending me messages and bombarding me with calls while I was in my private room, a place where it's impossible for me to build any common interest with anyone. There are only two possibilities to explain what X tried to do: he didn't know how strangers-interaction should be (which makes him stupid); or he wanted to create a completely new interaction (which makes him stupid as well). In other words, a stranger could not interact with another stranger, if: he wants to have a longer period of interaction; he doesn't interact in public places; or there is no mutual-short-term-circumstances. So, for me, there would be two possibilities as well: ignoring X completely because he doesn't act to fulfill strangers-interaction anymore; or responding to X that might lead to interaction that is completely different with strangers interaction. 

I chose the former (the latter doesn't even look like a choice, it's a nightmare).

Once a strangers-interaction is ended, there will be another series of  strangers interactions that are created and ended within seconds. They replace one another according to each person's mobility and interest. That's why, it was easy for X to jump from strangers-interactions into a new interaction that he tried to build. But at the same time, it was also super easy for me to jump to another strangers interactions without considering any of my interactions with any strangers in the past.
