Geoffrey Hampden has a lot of friends and is very popular at parties. Everybody admired him for his fine sense of humour, except his six-year-old daughter, Jenny.

Recently, one of Geoffrey's closest friends asked him to make a speech at a weeding reception. This is the sort of thing that Geoffrey loves. He prepared the speech carefully and went to the weeding with Jenny. He included a large number of funny stories in the speech and, ofcourse, it was a great success. As soon as he finished, Jenny told him she wanted to go home. Geoffrey was a little disappointed by this but he did as his daughter asked. On the way home, he asked Jenny if she enjoyed the speech. To his surprise, she said she didn't. Geoffrey asked her why this was so and she told him that she did not like to see so many people laughing at him!
