I must have the toilet roll facing out
I must park straight (very obsessive about this one)
I must not break my morning routine on work days. Things must be done in a certain order or it just doesn't feel right.
I must always sleep with a pillow underneath the covers
I must always clean up the kitchen before going to bed. I can't stand waking up to dirty dishes in the sink, unwiped countertops, etc.

I really am quite anal about alot of things but folding clothes is not one of them. I'm sure I'll think of more later on.
