A young man who lived in London was in love with a beautiful girl. Soon she became his fiancée. The man was very poor while the girl was rich. The young man wanted to make her a present on her birthday. He wanted to buy something beautiful for her, but he had no idea how to do it, as he had very little money.

The next morning he went to a shop. There were many fine things there: gold watches, diamond… but all these things were too expensive. There was one thing he could not take his eyes off. It was a beautiful vase. That was a suitable present for his fiancée. He had been looking at the vase for half an hour when the manager of the shop noticed him.
