One day a boy came to his teacher and said: Teacher, pa wants to know if you like roast（烘烤） pig.I certainly do, said the teacher, and you tell your father he is very kind to think of me.Days passed, and nothing more was said about the roast pig.Finally the teacher said to the boy: I thought your father was going to send me over some roast pig.Yes, said the boy, he did intend to, but the pig got well.
