imagine that you were near the swimming pool, where someone was almost drowned . describe what happened 

Such questions are meant to test your writing skills and should be attempted on your own. However, these points might help you elaborate:
- I joined swimming classes during my summer vacations.
- I had completed a month and could do one breadth of the pool, but the instructor was pushing me to start attempting a length of the pool!
- I was rather hesitant and scared to do that.
- One day, as I was trying to muster up courage to attempt swimming the length, I heard muffled cries.
- It was another child who was gasping for breath.
- The instructor had just gone out to attend a phone call.
- I knew that I could not wait for him to return: I gathered my wits and swam confidently towards the child who had started flailing his arms and legs.
- He was clearly panicking and that was making him gulp a lot of water.
- I held him by the arm and swam to one edge of the pool.
- I held on to the railing and shouted for help.
- Luckily, the instructor heard me and rushed towards me.
- He pulled the drowning boy out of the pool and then hauled me out.
- I was congratulated by him, thanked by the boy and his parents....
