　　When Mary was a student she always wanted to be a teacher because she liked children．When she was twenty-one years old,she began teaching in a small school．She was a good teacher and laughed a lot with the children in her class．They liked her teaching．One day,one of the girls in her class said to her,“Mary,why does a man's hair become grey before the mustache?” Mary laughed and answered,“I don't know,Helen．Do you know why it becomes grey before the mustache?” “I don't know,either,” answered Helen．“But it happened to my father．”

　　Then one of the boys said,“I know,Helen．Men's hair becomes grey first because it is sixteen years older than their mustache．”
