There is something good is everyone and you should be friends with everyone.
Dropped out of college at 21 then went back at 26 to finish. During that time I was very lonely and would hang out with anyone who was around. It's better to be alone on a Saturday night then to be with shytty people. The old saying "Misery Loves Company" is very true, I ended up hanging out and giving my time to miserable people and after a while I became miserable and I couldn't figure out why. It wasn't until I graduated from college got a steady job/life I realized I was unhappy. It took a year or two but after I stopped hanging out with those people my life finally started to become fulfilling again.
If people are passive aggressive, always like drama, chip on there shoulder and have negative things to say, do not talk/hang out with them. If you dont see this is the majority of people either you are in a good place or you one of them.
