Hmm.. quite difficult this one. Cos when you're alone and you're doing things you don't think about how wierd they are. But yeah, usually just dance around, sing loud, pulling faces in the mirror is a usual one. Think alot too. I like thinking, but not too much. That fucks you up.. I also like jumping around the room or fat lapping my house. Eeek, I do more when i'm bored and alone than I do when i'm with people!
