[00:17.48]Dentists always ask questions when it is impossible for you to answer. [00:25.00]My dentist had just pulled out one of my teeth and had told me to rest for a while. [00:32.31]I tried to say something, [00:34.47]but my mouth was full of cotton wool. [00:38.40]He knew I collected match boxes and asked me whether my collection was growing. [00:44.89]He then asked me how my brother was and whether I liked my new job in London. [00:52.98]In answer to these questions I either nodded or made strange noises. [01:00.04]Meanwhile, my tongue was busy searching out the hole where the tooth had been. [01:06.94]I suddenly felt very worried, but could not say anything. [01:13.52]When the dentist at last removed the cotton wool from my mouth, [01:18.76]I was able to tell him that he had pulled out the wrong tooth.
