Berries, I do the same thing. My mom's ex husband (he physically and emotionally abused me for years) was a military man. he had very high standereds in the way everything was done right down to the way the faucets were washed. I, to this day, cannot clean without worrying about a double check of my work. I can remember him saying "for every sock mismatched will be one lick with the belt." and that was when I was 6 yrs old! It is a very hard habit to break. Although I think mine is out of fear rather than a habit
