Why is it obligatory to entertain every random stranger who wants my attention and time? It's insane man, people randomly try to interact, especially in class. In class, it's been 6 months, I have said many times that I'm not interested in any social interaction with them, because they are not what I desire in social interaction, so, if a person is decent, sure, I will interact, but not these people who don't even talk nicely or make me feel safe.
