There are some people who feign interest in your personal life (and you have to throw them a bone otherwise face the charge of being boring or "aloof") but who will turn around and use their knowledge of things like your hobbies against you if they have a need.

I get that, I realized at my last job that if someone doesn't share my interest in nerdy things, they're likely to make some lousy assumptions about me if they know I'm really into things like video games and anime. We're often pegged as immature, irresponsible, or anti-social, which are qualities that can hurt one's…

I always used to... Mostly censoring how I was feeling, especially if it was negative, or any frustration I was having with things. I always felt I had to be positive and look and act like I was in top of everything.
