     The children next door often play the football in the garden after my house and sometimes

break my windows. Last Saturday afternoon I stay at home and read a book.After while,

I closed my eyes and went to sleep. A loud knock on the door made me wake up suddenly.

Soon a little boy turned out. "You haven't broken one of my window again?" I asked. "Oh, no!"

answered the boy. "Your windows are all opened this time and our football was in your bedroom.

Could you mind getting in to get our ball?" I was at a loss at the moment.
