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

    Recently, one of Geoffrey's closest friends asked him to make a speech at a wedding reception. This is the sort of thing that Geoffrey loves. He prepared the speech carefully and went to the party with Jenny. He had included a large number of funny stories in the speech and, of course, it was a great success. As soon as he had 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, Geoffrey wondered what Jenny thought of his speech.
