I was on holiday in Portugal last Summer with my family. It was very hot there. Everybody was enjoying themselves in the big swimming pool that was in the shape of the letter S. I heard a very loud whistle and it reminded me of something. All the memories came back. When I was four years old I fell into the deep end of a pool back home. The lifeguard blew his whistle that day and i heard the whistle again as a little girl went under the water. She was ok. I  learned how to swim after my fall.
