It was sunny and warm so Jane and I decide to go for a swim. When we got the beach, Tim, Paul and Mary were already here. We joined them and spent the afternoon swimming. The sea was as smooth as the mirror. I was pleased and Tim and Paul were a little disappointing as they like swimming in huge waves. When we got hungry, we bought hotdogs from a shop closely to the beach. After that, we had enough energies to play football on the sands. Paul and I won the game, in which surprised the others because we had three in their team. We really enjoyed the afternoon.
