Jane How did the quiz show go?
Pip Well, I came second to last, so at least I wasn’t the worst!
Jane Were the questions hard?
Pip Definitely. After the quiz show host had asked me for my name, he asked me what the capital city of Egypt was. I said Marrakesh, but I immediately knew it was wrong! I was so embarrassed.
Jane Couldn’t you remember?
Pip No! I’d even been to Cairo the year before – no, actually, I think it was the year before that. I went to Morocco this year, so I think I got confused! Then he asked how many miles there were in eight kilometres.
Jane That sounds difficult.
Pip Not at all. I know that five miles equal eight kilometres. Finally, he asked me when the Olympics had last been held in Greece.
Jane 2004 ... or 2006?
Pip You were right the first time! I said 2002. I’m not into sport! Anyway, it was disappointing, but not the end of the world. A week later, I got an email from Emir, the guy who’d won. He told me to phone him. When I did, he said that he wanted to share his prize money with the other five contestants! At first I didn’t believe him, but now I think it’s true.
Jane How kind!
Pip I know. I feel really bad about accepting it, though, because he was the one who won!
