I find myself counting the stairsteps in my house when I go up or down. Not ALL the time, but fairly often. There are 15 in case you wonder.
I do not leave discarded clothes on the floor of my closet if I am heading out to town. I at least fold them on the chair that I have in the closet. I think to myself, what if for some reason, a car accident or heart attack, I do not make it home and my daughter has to come down here to get my clothes and then sees how messy I live? (Sort of like that mom telling you to always wear clean underwear in the event you are in a car accident?)
I hate plastic but I still compulsively buy ziplock bags. Most of my stuff is stored in glass-lidded containers, so why do I keep ziplock bags? Some day I will make a list of when I use them and think of alternatives.
I put stuff away before the housecleaner comes so that all the surfaces are neat and tidy...it does make it easier for her to clean or dust.
I save all those stupid holiday catalogs thinking I will need them and stack them neatly on the couch near where I sit. That stack stays unmoved for weeks, and I have never ordered from any of them!
Each night I tell myself that I will be more proactive in getting things done the next day and it happens... about one out of every 8 days. (In all honesty, this is probably not just an old-timers thing.)
Got any unusual compulsive behaviors that others may notice but which are who you are?
