     Four years ago, when Mr Ted was sixty, he retired.  He left the restaurant in which he had worked

for forty-three years and returned to his home village. There he bought a small piece of farm and planted

a lot of apple trees in it. He took good care of them and this year there were plenty of apples on the trees. The old man was very happy.

     But these days the old man had been worried. Nearly every night this garden was broken into and

plenty of apples had been lost. So he decided to do his best to catch the thief himself. Last night he sat in

a tree and carefully watched who would come and pick the apples. At midnight, Mr Ted was so tired that he went to sleep. Suddenly some noise woke him up. The noise came from a big tree. He went there

gently and saw a boy standing under the tree with a bag full of apples.  At once he recognized he was

Tom who lived just next to him.

     "How can you do that, Tom?" the old man became angry and shouted." I'll tell your father about it! "

     But the boy wasn't afraid about it. He looked up and called out, "Have you heard yet, Dad? Mr Ted

has something to talk to you. "
