I have a compulsive need to touch doors before I open them.
Wait, hear me out.
I'm prone to static shocks sometimes, especially in winter, and somewhere along the line, I have picked up a habit of touching a door before I grab the doorknob, just to ground myself.
It's like I'm afraid that if I grab the handle I may somehow electrocute myself. Half the time I'm not even concious that I'm doing it anymore.
Well, I don't know about you, but I feel better having that off my chest.
