Talk about your unforgettable experience in life.

It was a terrible day even now I was cringe. Close to my home, there is a waterfall with a strong flow. People built a dam on it and made it became a lake. It was a sunny day when I decided to get to that waterfall with my friends. We climbed to the top of it which had become a lake. In there, we held a race that we swam to the opposite bank of the lake. It happened when I reached the bank and look back, I saw that the slowest boy suddenly was drifted along with the water flow. He too weak to swam through the flow so that he drifted along with it. Immediately, I shouted out, and the fastest one jumped out. He caught that boy and supported him to get to the bank. Then I threw a vine I had picked up nearby. The two caught it and were pulled out of the lake. My heart beats fast on all that day and whenever I remember about it. It was an unforgettable experience in my life.
