I sometimes have this weird urge to touch the corners of desks, or square objects. It feels really weird but it's like a recurring urge and I've even had to get up sometimes (watching TV with friends) to do it (usually I pretend I'm adjusting the TV)
Also, I hate pencils, if someone draws in a pencil the sound is like fingers on a chalk board, I hate there touch, I hate there sound, I hate them! For the last 4 years I've used pen
(Except in rare occasions where I am forced to use pencils, because there isn't a pen)
