I have a stalker!

Me: So let me get this straight. You left your keys in the car last night and today the keys were not in your car, so you used your spare keys?
OCD: Yes!! And when I went outside during my break my keys were in my parking space!! Has someone been calling about my hours? Asking about me?
Me: No. Let me just throw this out there... Maybe your keys were in the car and you didn't see them and when you got to work having used your spare keys to drive here, your actual keys fell out of the car and landed in the parking space.
OCD: No! It's a stalker. I think someone went into my car and took the keys then brought them here and left them next to my car after I went inside!!
Me: I really think you should calm down and consider my scenario. And just asking, why would you leave your keys in your unlocked car??
