Do you remember the man who helped you?

What I remember most is when I was twelve or thirteen years old. It was July and August in summer. I took a bath in the river ditch with some friends. At that time, I could not swim. All my friends have swam across the river. I didn't think the water was deep, so I raised my clothes above my head and walked opposite. Halfway through, I suddenly fell down and the whole person was completely submerged. Every time I call for help, I take a sip of water. Suddenly, a figure longed for swimming. I put my hand around his leg and felt that I was saved. When I woke up, I was in the hospital. A friend of mine saved me. Two other friends knew that I was scared away after falling into the water. I thought, what would happen if he ran away, too? He not only helped me, but also saved my life.
