Mr. Smith gave his wife ten pound for her birthday — ten pretty pound notes. So the day after her birthday, Mrs Smith went shopping. She queued for a bus, got on and sat down next to an old lady. After a while, she noticed that the old lady’s handbag was open. Inside it she saw a wad of pound notes exactly like the one her husband had given her. So she quickly looked into her own bag — the notes were gone! Mrs Smith was sure that the old lady who was sitting next to her had stolen them. She thought she would have to call the police; but, as she disliked making a fuss and getting people into trouble, she decide to take back the money from the old lady’s handbag and say nothing more about it. She looked round the bus to make sure nobody was watching, then she carefully put her hand into the old lady’s bag, took the notes and put them in her own bag.
When she got home that evening, she showed her husband the beautiful hat she had bought.
"With the money you gave me for my birthday, of course." She said proudly.
"Oh What’s that, then" he asked, as he pointed to a wad often pound notes on the table.
