例如: 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 was full of cotton-wool.
He knew I collected birds' 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 cotton-wool from my mouth, I was able to tell him that he had pulled out the wrong tooth.
