This is when my family and I were doing a road trip down to Los Angeles.
I was in downtown Los Angeles, doing the road trip by myself but with the same amount of stuff we had in the car. I parked the car on the street, at night, and I needed to throw out the garbage and do one other thing/errand, close by the car. For some reason, I thought leaving the car keys in the car and leaving the car unlocked was a good idea, although, in the back of my mind, I knew someone was going to steal it. Did the chores, walked back to the car, and chuckled to myself when I was that the car was gone.
