On a bus

  The bus stops(停) at the next stop(公共汽车站). A mother and her child get on the bus and sit down. The conductor(售票员) comes to them for the tickets(车票).   The mother says, "One ticket to the Children's Park(儿童公园)." The conductor looks at the small child, then says to him, "How old are you, little boy?"

  The mother wants to speak, but the conductor stops(制止) her. The boy says, ,"Mother says I'm four years at home and two on the bus." All the other people laugh(笑).
