Whenever I talk to someone, I always look at their nose.
I don't know why.
Sometimes I do this, and it's really bad in a serious conversation because then I start laughing at their nose for some reason and they are like " wtf this is srys " :P
Also, after a while of sitting here at the computer, I'll feel the need to walk downstairs and get something. Then I realize nothing is there so I go back up again and the cycle continues for a while.
There's other stuff that I can't think of right now.
