My dentist had just pulled out one of my tooth and had told me to rest for

while. My mouth was full with cotton wool. He knew I collected bird eggs and asks

me whether my collection was growing. He then asked me a lot of other question.

In answer to these questions, I could neither nod or make strange noises.

Meanwhile, my tongue was busy search out the hole where the tooth had been. I

suddenly felt very worried, so couldn’t say everything. When the dentist at last

removed the cotton wool, I was able to tell him of that he had pulled out the wrong

tooth.
