I went up to the roof for a break after studying for an hour and watched the 50 or so people swimming in the natural rock pool below our house. It was a sunny day-a blue, cloudless sky over a calm sea. But then, as I looked in the distance, I discovered a series of three or four big waves heading towards the shore. I'd seen the minitsunamis（海啸）many times before. They were heading at speed in the direction of the pool. Most people knew how to look out for them, but from the screams that started coming from the beach, I could tell someone was in trouble.
Without thinking, I ran down into the street, holding my toy boa（俯伏冲浪板）on the way and shouted at a stranger to go inside my house and call the coastgard. My neighbor Moises had heard the screaming as well and was also outside with his body board, so together we rushed to the steps that led down to the sea.
Once we got closer, we discovered the waves had pulled a boy and a girl from the pool and into the open sea. I knew that the nearest boat would take at least 30 minutes to reach us. Waiting for help wasn't a choice. I wasn't used to this sort of emergency-I'd never been trained as a lifeguard-but I didn't think twice about trying to save them. I supposed in a way I wanted to impress everyone: at 19, a deal like that can seem like a good opportunity to show off.
Moises and I dived into the water and it took us 10 minutes to get to them. When we finally reached them, they were almost lifeless with only their heads coming in and out of the water. We could tell they were still alive from their small breaths but it was clear they wouldn't have been able to stay there much longer. I hold the boy and pulled him over my board. Moises moved the girl on to his board. We discussed pushing them back to the shore, but we were too far out.
