Very good read. I was a life guard for 5 years and only saw 2 people need to be rescued. I had no idea what was going on during the first one because everything seemed normal. the girl didn't realize the pool floor was movable and it was deeper than it was the day before, she took one step off the sloop towards the ladder and her head went under. The life guard closest to her realized what was going on and was about to jump in before anything bad happened. No more than 30 min later another kid did the exact same thing.
