I always eat Skittles in pairs with matching colours (ie, two yellows) and if it's an even number I have to eat them with a colour that is nearest the other colour (ie, yellow and green, red and purple, red and orange, never orange and purple), however, I like to eat pasta in groups of three. I also find myself talking to myself an awful lot, not in public, but in my room, at the computer/TV. I do the sign-post thing too. I also hate when there is a stack of books somewhere, (library, misc. waiting room, etc) when the smaller-sized book is placed underneath the larger book; I rectify this and order them according to size, even with pieces of paper, or reciepts in my bag. That's all I can think of right now.
