    My daughter is a single parent, whose life is very hard because she has three young sons. She plans her money carefully and manages to get something expensive that many people can buy easily.

When her eldest son, David wanted a bicycle so that he could do an after-school job, the family saved up and soon he was the proud owner of a good second-hand bicycle. One afternoon my daughter asked David to go shopping. He rode his bicycle, but carelessly left it outside the shop without putting on the lock. When David came out of the shop, it was gone. He walked home in tears and then, together with his angry mother, went to the local police station to report the theft.

Imagine their joy when they arrived at the station, a car parked out front had David’s bike in the boot (后备箱). The driver told my daughter how he’d seen a group of kids go for the bike once my grandson had gone inside the shop. The driver had called out to them to leave the bike alone. Instead, one of the kids in the group had jumped on the bicycle and ridden it away while the others followed.

The driver got in his car, drove after them and brought the stolen bike back. He was happy to be able to return it to my grandson together with a lesson about the mistake of failing to use the bike lock. Then, in all the excitement, he drove away without even giving his name or telephone number.
