No, I'm probably the nicest while I'm on here. XD Or the rare cases when I want to get to know someone on a different website. It doesn't say much, but considering that I go to 4chan to hate on christians, americans, etc. I'm actually pretty decent here. I have a FB, but I barely use it for anything else than spamming music videos and liking stuff, so I remember what I've watched before.
I wouldn't say that I'm the closest to my real life self here. Quite a lot of people think I'm a girl for one, but I do have a few friends on this site, who does know what I'm really like.
