One morning a boy was going by a London bus to school. He had a cold and was sniffing all the time
and so loudly that the people bagan to look at him and shake their heads.
An old gentleman was sitting next to the boy. He suffered the boy's sniffing for some time but at last lost his patience and said:
"Haven't you got a handkerchief, my boy?"
"Yes, I've got a clean handkerchief in my pocket," said the boy, "but I can't let you have it.
Mother says it is not polite to ask anybody for a handkerchief. You must use your own."
