    Before Christmas Mr Smith broke his right leg and had to stay in hospital. When he was there, he always

asked his doctor when he could go home. He didn't like to spend Christmas in hospital. Though the doctor

did his best, Mr Smith didn't get better. So on Christmas Day he was still in hospital. He spent a bad day in

bed thinking that he missed a lot of fun on such a happy day.

   The next day the doctor told him that he might be well enough to leave hospital in time for the New Year.
