Good deed day

While passing a neighbours on the dog walk, I noticed their robot mowing machine was not moving. It was stuck in a dip with its poor rear wheels turning away but going nowhere. I decided to help it by nudging it with my foot. It seemed to help, the rear wheels got the grip it was seeking. It spent a short while figuring out what had happened and then tootled off mowing away. No word of thanks came my way. Ungrateful machine.
