A well-known manager（经理）loved his only son very much.
However，the son was very foolish and often made others unhappy in public（当）by his impolite language.
Once the father was invited to a party and the son asked to be taken to it with his father."No，"said father，"This is a party for the first birthday of the richest man's son here.I'm afraidthat you would…”"No dad，"the boy promised his father，"I'm sure not to say anything rude on the party."And then the boy attended the party，He kept his promise for almost the whole party，but when the party was over and all the guests stood up，he stood up，too，and said，"You know，everybody，I haven't said anything ill today，if the child dies this year，it will have nothing to do with me."
