I was away from my car for a little over an hour. When I returned, my heart nearly sank to my stomach when I saw it sitting there with the windows down.

I'm way more careful now because of it, but I sometimes have a nagging suspicion that my car is unlocked as I'm walking away from it. It always happens when I'm just far away enough that the remote doesn't work.
