Last night our next door neighbor came over to tell us that her car was stolen out of her driveway that morning. It was a very cold morning, and she started her car to let it warm up. She was actually outside waiting, but ran into the house for a few seconds to grab something. When she did, someone jumped into her car and drove off with it!
Apparently, whoever stole it was watching and waiting. It only took a few seconds and it was gone.
When I think of how many times I have done this (the car warming up thing, not the car stealing thing!) it makes me cringe. Never again.
