A lot of my friends do this a lot, and go way overboard with it, some of it is really just petty and bitter, like I don't really feel either way about it, esp. if it's just someone working a normal job, or having kids, whatever.
Sometimes it's some funny shyt, like the douche cool guy, (who you were friends with) losing his mind on ectascy and becoming even dumber. But, when one of my boys comes with some story like 'I saw ____ working at (random restaurant) fukk THAT bytch, she thought she was so much better then everyone else'. I was like, she went to college, graduated, and is living at home, working a temp job, it's not that serious. You still live at home too lol. And didn't even graduate.
People who I wasn't friends with, or wasn't involved with, just paid them no attention, they hardly existed then, and they exist even less now, to me. i am always down to her some funny stories or gossip about whoever, but just bringing people down for no reason, or for some perceived slight in fukking high school 8 years ago let that shyt go, it's unhealthy.
