Sounds like people don't like you, so you retaliate & don't like them. If you look so pessimistically at people, the bad ones'll stand out. & especially if you get jealous at the cool people that exist, so don't bash ol' hippy, goddamnit. Yer attitude is scary, man...chillll.
What the hell? contribute? society? including you in that society? Say NO, don't give a shit, you're on your right of being a 15 sucker and feeling what your little brain wants to feel.
pain is the best teacher there is, and just because so many people are not as loving as you would like, it is no reason to execute them. Don't worry, the laws of natural selection and overconsumption by us will take care of it soon anyway.
