Chicken bones really really really bother me. Like I practically gag just thinking of them. They always look terrible after someone is finished eating, they sound horrifying when they get snapped, it's just all around a really bad time.
I hate running into people I know when I'm not expecting it. Like just by chance somewhere randomly. You have to do the whole "omg how funny, you're here too? how you beeeen? wow long time no see! you look great!" and really I don't care I just want to do what I'm doing.
