A visit to the beach
It was a sunny day when I went to the beach. The sea was calm. There weren't people around, but birds were flying in the sky. I was walking along a cost without any thoughts in my head, but one thought suddenly crossed my mind. I remembered as I fell in love with the sea. When I was a child, my parents and I went to the beach almost every day for a walk. We are used to living near the beach. I was able to see from my window as blue waves moved across the surface of the sea and broke over cliffs.
