This is so incredibly aggravating to read lol

as someone who doesnt know shit about interacting with people because i've never had any friends or been in a professional environment i liked it but at the same time it could sound self-aggrandising

why?

He's bragging about being polite, there's some points where he admits to being extremely insincere and that bugs me a lot (I don't want to think that people are just being polite when they seem to be into what I'm saying!!), and there's no actual breakdown of these are the basics of being polite. It doesn't really have a structure, it's basically a rant.

he isn't insincere though; he admits to finding these people interesting once he gets the conversation going. I'd rather have someone listen to me, even if their enthusiasm is slightly feigned, than to dismiss me immediately. I might have a chance of getting along with them then.

I do agree with your other points though.
