This may not be what your asking but I think its a weird habbit. If I scratch one side of my head I have to do the other. Or one ear, cant neglact the other. If I pick one nail to get the gunk out I have to do all of them, fingers and toes. Even if I have just locked the door a few hours before, I have to check them before I can get to sleep. I have this routine I have to do before I can get to sleep too, or at least feel comfortable in bed. Like checking all the rooms, making sure the lights are off stuff is up (even if i already know I did it) doors locked, go to the bathroom, make sure the hubby is all covered and the dog is there. Like I said may not seem weird but the way I do things I think its weird.
