Last Saturday I went to the library as usually. At about noon, I was enjoying my reading near a lake while suddenly I hear someone crying for help. I went up to see what was happened. I was shocking to find a little child struggling in the water in the distance while many peoples were standing by without doing anything. Without any hesitation, I had pushed through the crowd as I took off my coat, but jumped into the water quickly. I managed to reach him and carried him back to safety. To his great relief, the kid was saved.

I am proud what I did. I hope everyone can give a hand when someone else is in need.
