 The story of why I learnt to swim is interesting. Three years before my father and I went for swim. While my father was changing his clothes I am walking along the side of the pool. Suddenly I slipped into the pool. I was too afraid that I shouted at once. The water kept come towards me. Although I was afraid but I struggled very hard to keep my head above the water. In my surprise I was able to keep doing it. Just then my father saw me and said “Calm down. Just wave your arm and legs like this. Right !” And I got it. I final learnt to swim.
