One day, during the school holidays when I was a young teenager, I rode my bike to a popular children’s play area in the next village. There were lots of other kids there but I became interested in the activities of one group in particular. This gang was two girls and three boys.
The girls were aged about ten, and so were two of the boys, but the last one was about five, perhaps younger. He was clearly the younger brother of one of the girls, and she was not pleased that she had been made to look after him at the park. I learned from the conversation that his name was David, and she was Sarah.
