A father and his baby
One Sunday some visitors to Hyde Park, who were sitting on benches quietly enjoying their sandwiches, were suddenly surprised by a strange young man.
The young man was pushing a pram. The baby in the pram was crying loudly. The young man stopped and said softly, "You should take it easy, Tom. You should control yourself, Tom." The baby calmed down for a minute but then it started to cry again. The young man stopped, took out a little toy out of the bag, gave the toy to the child and said, "You should take it easy, Tom. You should control yourself, Tom."
They went on, but soon the child started to cry again. The young man stopped, took some chocolate out of his bag and gave it to the baby. "Don't worry, Tom. It's OK, Tom. You'll be all right, Tom," he said. But the baby didn't calm down. It just cried louder and louder.
An old woman who had been watching the man came up to him and smiled. "You're a great father," she said, "You know how to talk to your baby, in a nice, quiet voice." Then she looked into the pram and asked, "What's wrong with you, Tom? Why are you crying?"
The father looked at the woman strangely and said, "The baby is a girl. Her name's Sabrina. Tom is my name."
