Do you wanna know what the three things I particularly hate? Meetup.com, Tumblr, and scumbags who tell me to join social grouops even though I have a hard time fitting into them. Someone tell me, WHY DO THEY HAVE TO EXIST IN MY LIFE?
Some actually socialize well. But from what I've seen, it's often a combination of experience and them being used to each other since they've attended more meetups with each other compared to with me.
I don't think I would ever go to anything like that. I would just want to find an excuse to leave after a few minutes, or not even show up and try to BS my way out of it if someone from there tried to contact me.
