A few years ago I had purchased another car since my old one was not going to last long.
I still had my old car and had not gotten rid of it yet when this happened.
Each day I would drive to the next town and park my new car in a residential area and walk a few blocks to get to work.
On the way, I noticed this one car that was identical to my old car except for different color and that it also had one missing hub cap.
One morning that week, I took a hubcap off of my old car and put it on this car that needed one and walked off.
I never saw the owner and the owner never saw me.
