Mary was seven years old. Her parents recently moved to a new town, and so Mary was going to a       school, which was a few kilometers from the house they lived in now. A school bus going around picked up        every morning and brought them back to their      every afternoon, and as both of Mary’s parents        to go to work, she always went on this bus.
Mary’s parents always      their alarm clock for seven o’clock so that none of them would be        . But one morning the alarm      to go off, and it was not until a quarter past eight that Mary’s mother suddenly      , looked at the clock and said, “What’s ever happened to that clock?” and then        into Mary’s room to wake her up.
“I’m sorry, dear,” she said, “       you’ll have to wash and dress very quickly, have an even      break-fast and then I’ll         you to school on my way to the office.”
“But how can you find the      , Mum?” Mary said, “You’ve been to school only once.”
“Yes,” her mother answered, “but you’ve done the        several times now on the bus, so you can be my guide to get there, can’t you?”
“Oh, yes,” said Mary, “I suppose so.” She washed, and        and had a quick breakfast, and then they set off. Mary told her mother to turn each time they came to a place she         . In this way she made her mother drive round most of the town       they got to her school. When they arrived, her mother saw that it was not really very far from her house.
“Why ever did you make me go such a long way round, Mary, instead of the most          way?” her mother asked her.
“Well, Mum,” answered Mary, “it was because I didn’t know       else to get here. That’s the way our bus always goes to        the other children to school.
