Hope you are finding the answers you need 12years.
For myself, it is strange. I have the craziest relationships with people for little to no reason. There is one guy who I only talk to when we are in class, and even outside of class, no recognition. I don't mind. Then there are a few people who i talk to them about pretty much 2 things, games, homework, and nothing else.
You find the craziest connections in the craziest of places. I'm not sure if this is helping, but connection is a pretty open word.
In the context you are speaking of though...I can agree that I play the nice polite guest with people I don't know. I guess its just part of how we just go through society, makin everything look nice. The only people I've really connected with have seen my darker side...so in that respect, you gotta give it to get it.
