Three Umbrellas

Sally was a college student in London. She wanted to buy her mother a nice and useful birthday present, but not too expensive.

One day after a quick and simple lunch, she went shopping. Having looked for half an hour, she came across a shop selling umbrellas at a good price. So she decided to take one.

She thought, “Mom can carry it when she is wearing clothes of any color.” Then she bought a lovely black umbrella and took it to school with her until her class finished.

On her way home in the train that evening she felt hungry, so she went to the buffet car.  She left the black umbrella above her seat. But when she got back, she found it was gone! 

Sally burst into tears. The other passengers felt very sorry for her and asked what was wrong. When she explained the black umbrella she had bought for her mother had disappeared, and that she had to get off at the next station, the three other passengers asked her for her mother’s address so that they could send the umbrella to her in case someone returned it after Sally got off the train.

The next week, Sally got a letter from her mother saying “Thank you very much for your lovely presents, but why did you send me three black umbrellas?”
