OCD

turn the car around. I gotta go back home.
what? why?
I gotta check to see if I left the lights on.
dude, you turned them off. I saw you.
I'm not sure. I have to go back. turn around.
but that's crazy! I saw you!
well, I may not have locked the door.
what is this with you?
it's my OCD. drives me nuts.
can't you just trust me?
I do. but I'm also not sure I washed my hands.
