Tell me.. what are you "anal" about?

[Clairity]

Is there something that you always say or do without thinking about it and because you just always have? I always sort my dollar bills smaller to larger and they all must be facing the same way (face forward). I always take the foil that gum comes in, fold it in half and then fold it again before throwing it away. (I guess just crumpling it up would be too much work.) Ok.. your turn.. come on.. unburden yourselves! .
