Mr. Smith went on a business trip to London and three of his friends asked him if he didn't mind buying umbrellas for them. Mr. Smith checked in at the hotel, left his luggage and decided to go to the shop. For nearly a fortnight it poured in London, and on that day the weather was nasty too: it was raining hard, a strong wind blew, and there was no hope that the sun ever appear. So Mr. Smith fetched his umbrella and putted his raincoat on, because he was afraid he would get wet through.
To Mr. Smith's disappointment all the umbrellas were sold out the day before, but the owner of the shop said they had no supply for a long time and he was sure he was getting some umbrellas in the afternoon. At the time Mr. Smith left the shop it was no longer raining, the sun was already shining brightly, and one could hardly believe that some ten minutes before it rained cats and dogs. Mr. Smith left his umbrella behind, but the weather was so fine that he even didn't remember about it.
He got on the bus that could take him to the hotel, but when he got off the bus, by mistake he took his neighbour's umbrella and suddenly he heard the man say: "Sorry, sir, I believe this is my umbrella." "I am sorry, sir," said Mr. Smith, he felt ashamed - the people could think he was a thief - and he hurried out of the bus. He came to the hotel, had dinner, and in the evening he went to the shop to buy umbrellas. He bought three umbrellas and the owner returned him the umbrella he left behind, and when he returned with the four umbrellas in his hands, he met the man whose umbrella he took by mistake when he left the bus. The man smiled at him and said: "You had a lucky day, eh?"
