Fred is an eleven-year-old boy. Today is Friday. His friend Jenny's twelfth birthday is coming. Jenny says to him, "I' m going to have a birthday party on Sunday, Fred. Would you like to come?"
Fred asks his mother about this. His mother says, "Sure, you can go to Jenny's birthday party." On Sunday afternoon, his mother says to him again, "Now, Fred, when you go to the party, remember this: you must be polite(有礼貌的), and don't ask for food until someone gives it to you."
"All right, Mum," Fred answers, and he goes to Jenny's house on his bike.
There are many children at the party. They play for an hour and then Jenny's mother gives them some food, but she forgets Fred and doesn't give him any. He waits politely for a long time, and then, he takes up his plate and says loudly, "Does anyone want a nice clean plate?"
