I am not very social around people I do not like, wbu?

I just go behind their back and learn everything about them. I'll pretend to be their friend but it's about what they come from. I have to know them by their movements. body language. behaviors

I had to learn to be less 'approachable' for people I don't like.

mostly not,then at days too much. but most definitely not

I'll be polite but quiet as I cant wait to get away from them.

I'm somewhat shy

I can’t really disguise it well if I dislike someone. I see no reason to be fake.
