Weird, but true. Who are you?

I am the girl who:

  1. Looks for the dead body on the floor EVERY time I open the door to a public restroom, of any kind. I am mildly surprised and relieved when it's just a dirty floor.

  2. Often imagines how EASY it would be for any person passing me - or you - in the street, or standing beside me or you at a concert to shank us and kill us. We have so much trust in our fellow man just to leave the house.

Who are you?
