My dentist had just pulled out of my teeth and had told me to rest for a while. I tried to say anything , my mouth was full of cotton wool. He knew I collected match boxes and asked me that my collection was growing. He then asked me about my brother and whether I like my the new job in London. I either nodded or made strange noises in answer for the questions. Meanwhile,my tongue was search out the hole where the tooth had once been. Suddenly I felt very worriedly, but still could not say anything. When the dentist at last removed the cotton wool into my mouth, I was able to tell him that he had pulled out the wrong teeth.
