A mother and her young
son get onto a bus in a city and sit down. The bus conductor comes to them for
their money. The mother says ,"I want one ticket (票) to the zoo." Then she gives the conductor
the money. The conductor looks at the small boy for a few seconds and says to
him, "How old are you, young man?" The mother wants to say something,
but the conductor stops her, and the boy says, "I'm four years old at
home, but two in buses." The mother's face turns red. She has to give the
money of another ticket to the conductor.
