One of my OCDs are that I HAVE to turn off every plug I see that is not in use..
I can't wash dishes barefoot
I can't let my body touch the duvet or the actual bed cover
If I'm turning up the volume, the volume can only be on 5 related numbers
( 5, 10, 15, 20, 25 ect ) LOL most of the time it's either too low or too high but I prefer it that way then if it's on any other related numbers..
