I don't like socialising, and I especially don't like it when the people i'm socialising with don't get it (you're sitting their thinking they don't care or something)
I also have an intense fear of people collapsing (I've written about it a few times), so I find myself unable to stay around someone for too long, even if I know they are healthy and well.

litirally the only reason I'll be around someone is because I have too (like an appointment or something). I don't like people. it's as simple as that
