Do you do any "small" things that bother you a little bit but not enough to change. When I wash my hands after playing with my cats or changing their litter, etc. I use my husband's towel instead of my own to dry my hands :-) It makes me feel a little guilty (but my hands are clean?!) but I have a "thing" about when I shower, wiping my face, say, on the towel where I've dried my hands after a "dirty" experience.
