First listen and then answer the question: Why did Elizabeth tell Nigel that she was going to the dentist?
I crossed the street to avoid meeting him, but he saw me and came running towards me.
It was no use pretending that I had not seen him, so I waved to him.
I never enjoy meeting Nigel Dykes. He never has anything to do.
No matter how busy you are, he always insists on coming with you.
I had to think of a way of preventing him from following me around all morning.
"Hello, Nigel," I said. "Fancy meeting you here!"
"Hi, Elizabeth," Nigel answered. "I was just wondering how to spend the morning -- until I saw you.
You're not busy doing anything, are you?"
"No, not at all," I answered. "I'm going to..."
"Would you mind my coming with you?" he asked, before I had finished speaking.
"Not at all," I lied, "but I'm going to the dentist."
"Then I'll come with you," he answered. "There's always plenty to read in the waiting room!"
