Robert was born in a small town in England. His father has a farm and can supply him enough money to finish university where he's studying law. The young man studies hard and hopes to be a famous lawyer.

Last Monday their term was over. Robert said to his father on the telephone that he was going to travel in a small country during his summer holiday. His father agreed to his plan and posted some money to him. So he started four days ago. Their plane landed at the only airport of the country safely. He took a taxi and got to a hotel in the centre of the capital. He felt hungry and tired. So he had a dinner and then a good sleep. This morning he was all right and was going to visit some places of interest. He met an English visitor while he was having breakfast and the man told him to be careful of thieves.

Robert thanked the man and left. But he thought he was smart（机灵的）and strong and he decided to have a try. He brought out a piece of paper and wrote on it, “A pig has stolen my wallet（钱包）!”Then he put the note into his empty wallet. After that he put the wallet into a pocket and set off. He did all carefully and hoped to find out who would steal it.

“Everything went well, ”Robert thought to himself after he had returned to the hotel. He brought out his wallet and put his money into it again. He had a look at the note. To his surprise, it was rewritten. It said, “Your uncle has touched your wallet!”
