Why did the writer become very worried?
Dentists always ask questions when it is impossible for you to answer. My dentist had just pulled out one of my teeth and had told me to rest for a while. I tried to say something, but my mouth waw full of cotton wool. He knew I collected match boxes 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 answered to these questions I either nodded or made strange noise. Meanwhile, my tongue was busy searching out the hole where the tooth had been. I suddenly felt very worried, but could not say anythin. When the dentist at last removed the cotton wool from my mouth, I was able to teel him that he had pulled out the wrong tooth.
