Yeah but how haven't you heard about the amazing game that is tf2 yet

It's just more personification of objects as long as you don't act based on their "judgement"

It's fine you had a really bad experience you are probably tramautized by it

That's fine not many people like them but it's not bad for you and if you like it then keep doing it

No your sister shouldn't do that that's just a dick thing to do but your reaction was normal humans are a very superstitious species

Nobody should be taking and throwing away your stuff now that you are an adult it's your property and not theirs to destroy

It's not normal or healthy you should explore any likes or dislikes that won't harm you or otherd

Try seeing a therapist or any mental health expert
