英文小作文：

When I was young, I often played with my friends in the park. We would run around and have fun, but sometimes we would get tired and need a break. One day, we decided to sit under a tree and rest. It was a beautiful day and we could see the sky and the clouds moving slowly above us. We were all feeling a little out of sorts, but it was nice to just sit and relax for a while. We could hear birds singing and see butterflies fluttering around us. It was a perfect moment and I will always remember it.
