He is an overly curious person and does almost everything to see what kind of reaction he will get. He is also bored a lot which causes him to post a lot of random stuff. He is actually a really good guy, very giving and will do anything he can to help a brother out. He has been known to be a little sensitive and will do anything to please others, even if that means being selfless. He can be a bit bi-polar but is really pretty harmless.
Yup, that should be added as an option. I know myself too well.
