My wife was wearing a hat that looked like a lighthouse !Mrs Anne Sterling did not think of the risk she was taking when she ran through a forest after two men. They had rushed up to her while she was having a piic at the edge of a forest with her children and tried to steal her handbag. In the struggle, the strap broke and, with the bag in their possession, both men started running through the trees. Mrs Sterling got so angry that she ran after them. She was soon out of breath, but she continued to run. When she caught up with them, she saw that they had sat down and were going through the contents of the bag, so she ran straight at them. The men got such a fright that they dropped the bag and ran away. 39。 I am 100 per cent honest now!39。 eggs and asked me whether my collection was growing. He then asked me how my brother was and whether I liked my new job in London. In answer to these questions I either nodded or made strange noises. Meanwhile, my tongue was busy searching out the hole where the tooth had been. I suddenly felt very worried, but could not say anything. When the dentist at last removed the cottonwool from my mouth, I was able to tell him that he had pulled out the wrong tooth. t know where it is.39。 said the conductor suddenly.39。My friend, Herbert, has always been fat, but things got so bad recently that he decided to go on a diet. He began his diet a week ago. First of all, he wrote out a long list of all the foods which were forbidden. The list included most of the things Herbert loves: butter, potatoes, rice, beer, milk, chocolate, and sweets. Yesterday I paid him a visit. I rang the bell and was not surprised to see that Herbert was still as fat as ever. He led me into his room and hurriedly hid a large parcel under his desk. It was obvious that he
