Last weekend,Tom went to visit his friend in Paris.Tom 71 at the bus station quite early for Paris bus.The bus for Paris would not leave until five to twelve.He saw a lot of 72 waiting in the station.Some were 73 in line,others were reading .There was a group of 74 .Their teacher was trying to keep them in line.Tom looked 75 but there was no place for him to sit.
He walked into the station cafe .He looked up at the 76 there.It was only twenty to twelve .He found a 77 and sat down before a large mirror on the wall.Just then,Mike,one of Tom’s workmates came in and sat with Tom.
“What time is your 78 ” asked Mike.
“There’s plenty of time yet,” answered Tom.
“Well,I’ll get you some more tea then,” said Mike.
They talked while 79 ,then Tom looked at the clock again.“Oh!It’s going backward ” he cried.“A few minutes ago it was twenty to twelve and now it’s half past eleven.”
“You’re looking at the clock in the mirror,said Mike.Tom was so 80 .The bus was not to leave for another hour.Since then Tom has never liked mirrors.
