Some years back, when my boyfriend had his beloved first car, the license plate had "DUD" as part of the registration, so you can imagine how beat-up this car was.
Anyway the car had run out of petrol about 1/2 mile away from our house - and somehow through playing the car stereo, the battery had run flat. Through the help of a friend we got some fuel and enough juice in the battery from a jump start. We still had to push the car up a small bit quite steep hill to get it home.
The three of us were having difficulty pushing, when all of a sudden in this country lane, a man appeared, and helped us push the car to the top of the hill. We thanked him for his help, and he went on his way. When we looked around a few steps onwards, to yell our thanks again - the man had vanished.
We still think it a mystery, as we never heard or saw the man approach us until he appeared by our sides. I still think of him as an Angel and thank him for his help.
