One morning a London boy was sitting in the bus on his way
to school. He was sniffing all the time and making noises with his nose that
the other people in the bus began to shake their heads.
At last an old man who was sitting next to him said, “Little
boy, have you got a handkerchief?”
“Yes, I’ve got a clean handkerchief in my pocket,” said the
boy. “But I can’t let you have it. Mother says it’s not polite to ask anybody
for a handkerchief You must use your own.”
