Tom arrived at the bus station quite early for the London bus. The bus for London would not eave until five to twelve. He saw a lot of people waiting in the station. Some were standing in lines, others were walking about. There was a group of school-girls. Their teacher was trying to keep them in order. Tom looked around but there was nowhere for him to sit.

He walked into the station cafe. He looked up at the clock there. It was only twenty to twelve. He found a seat and sat down, facing a large mirror(镜子) on the wall. Just then, John, one of Tom's friends, came in and sat with Tom.

"What time is your bus?" asked John.

"Oh, there is plenty of time yet, "answered Tom.

"Oh, I'll get you some more tea then," said John.

They talked while drinking. Then Tom looked at the clock again.

"Good heavens! It's going back-ward!" he cried. "A few minutes ago it was twenty to twelve and now it's half past eleven."

"You are looking at the clock in the mirror," said John.

Tom wanted to kick(踢) himself for being so foolish. The next bus was not to leave for another hour. He has never liked mirror since then.

     On January 15, a little girl from the Chinese mainland was on the subway in Hong Kong. She

was eating something. A local man told her not to do so. The girl's mother told him to mind his

own business. A quarrel started. Hong Kong Mass Transit Railway rules say people cannot eat

on the subway. The rules say the train will be filled with the smell of food. They say the smell will

attract mice to the train. These mice might chew the cables and cause safety problems for passengers.

People caught eating on the subway will be fined up to 2,000 Hong Kong dollars (1,625 yuan),

Xinhua reported. Signs clearly say "no eating" and the rule is often announced on the subway and in

stations. However, the girl and her parents say they did not notice this.

     This seemingly small event has started a debate on the Internet, Xinhua reported.

     A netizen named Zhu Hongying said some Chinese consider bad habits like talking loudly in public

places, spitting or jumping queues as small matters. They simply don't care because they think public

places are not their private homes. "This kind of thinking shows a lack of a sense of social morality,"

she pointed out.

     Many people agree. "The parents (of the girl) should have apologized for their mistake," Zhang

Nan, 15, a Senior 1 student at Diaotai High School, Shaanxi, said to Teens. "Quarreling after making

the mistake only makes the situation more embarrassing for them."

     Reports of Chinese people behaving badly at tourist sites at home and abroad are nothing new.

Such reports are affecting the way other countries see Chinese people. Some foreign airports put

up signs in Chinese telling Chinese people not to talk loudly and not to spit everywhere. Many

Chinese people find this embarrassing.

     All this shows that one of the secrets to a good journey is to learn about local customs and

taboos before you go.

A. something you buy or keep to remind yourself of a place or an occasion
