On Thursday last week, I and my friends went to the water park. Here I was with my friends doing a good job. It was a small help, but to me it was very meaningful. I remember as it was that day. Last Thursday, my school was out of power so the whole school was off. My group just went out to play in the water park. That morning, from 9 in the morning we departed in a good mood. As I finished swimming, I and my friends ran to the pool. Feeling hot, mercilessly cool streams in the lake away. The atmosphere was very loud, the sound of water flowing down the lake or the artificial waterfall made us excited. Looking around the colorful slides, buoys of all shapes are fun to float on the water. Artificial waves slowly hit the shore, causing people to float in cool water. Everyone and all the scenery are enjoying themselves at the invitation of the lake. At this time, the bright sunshine of the summer afternoon was eased away. While everyone was playing happily, there was a girl around seven years old crying from afar. So we ran to him and asked. She has an oval face and large round eyes and pink skin gave me a great impression the first time I met her. She was crying and we were embarrassed, no one knows how to comfort her. At that moment, Hoa came to sit next to me. Flowers smiling at me, just patted her shoulder, Hoa just comforted her. After a while, she stopped crying and told us about her lost mother. As soon as we heard the news, we immediately took him to a large pool round to find her mother. But due to the overcrowding, I and you can not find him right now, she seems very disappointed, in her eyes showing anxiety and fear. Look at those eyes that I love you too! In my mind, I'm thinking of ways to help you lessen that fear. I immediately suggested that you would let him play with us. You all agree. Our journey and the little girl started on the seven-sided, spiral-shaped skates. Before she slid, she seemed a bit scared so I hugged her in the arms to slip with me. Water followed our slip speed that splashed. After a lot of slides with me and you seem to have been a little sad and worried. Time to play with the slide also has passed. We continue to sit on the float to float down the river. The bold feeling in the water of the slider is no longer here but now we are quietly dropping. Then we switched to colorful balls and many underwater games. An hour passed, now I smile back. Your eyes are no longer buried in the frightened pot anymore. It's time to return to finding her mother. We were lucky to find him. The girl was breaking up in happiness because she met her beloved mother. After saying goodbye to the little girl, we ended up having fun together. Just arrived home, I told her immediately. Mom laughed and complimented me a lot. My mother's smile shows satisfaction and pride.

It was a great pride for me. That day, I had a good time playing with her. I made my mother feel proud of me. That's what I always wanted to do for my mother. I will try to do more good things to bring her a lot of fun.
