He found a seat and sat down before a large mirror on the wall. Just then, Mike, one of Tom's friends,

came in and sat with Tom.

    "What time is your bus?" asked Mike.

    'There is still 15 minutes left," answered Tom.

    "Well, we have enough time to have a cup of tea ,"said Mike.

    They talked while drinking. Then Tom looked at the clock again. "Oh! It's going backward (向后)!"

he cried."A few minutes ago it was twenty to twelve and now it's half past eleven."
