This is Mary and her mother.
Her mother says she can’t go out to play until she has done her three chores.
At 1pm her friends come over and ask if she can come out to play.
Mary says ‘I can’t, I have to do the dishes.’
So she does the dishes.
At 2pm her friends come over again and ask if she can come out to play.
Mary says ‘I can’t, I have to sweep the floor.’
So she sweeps the floor.
At 3pm her friends come over again and ask if she can come out to play.
Mary says ‘I can’t, I have to chop wood.’
So she chops wood.
Mary goes to her mother and says ‘I did all my three chores.’
Her mother says ‘You are allowed to go out and play now.’
So Mary runs outside.
But she falls down on the steps.
And she breaks her leg.
At 4pm her friends come over again and ask if she can come out to play.
Mary says ‘Well my mother said I’m allowed to,’
‘… but I broke my leg, so I can’t.’
