Car paranoia:
Car keys in between my knuckles
Look to see if anyone's under my car (sometimes)
Look in the backseat to make sure no one's hiding back there
Lock the doors as soon as I'm in the car
Lock the doors every time I get out, even if I'm just pumping gas
Don't park by a van
Always park underneath a light
Pepper spray and a whistle on my keychain, and one of those windshield-sunlight-blocking signs that says "Call Police" just in case
Wear my purse strap across my chest (not hanging off one shoulder)

Home paranoia:
If I'm really scared, I leave the TV on all night
All doors and windows are always locked
Blinds drawn tightly shut at night
Always check through the peephole before I open the door, even if I think I know who it is
If the buzzer sounds (I live in an apartment and you have to be buzzed in the building if you don't have a key) and I'm not expecting someone I make my boyfriend answer it (I don't want anyone to think I'm a girl home alone)
When I'm leaving the apartment, I lock the door, then turn the knob to make sure it's really locked

Ummm...could I be any more OCD?
