#Person1#: I heard something terrible happen to your son last weekend.
#Person2#: Yes, my family went swimming with Mr. Henry and his son last Saturday. When we got there, my wife and I started looking for a nice spot near the pool. My son ran off by himself and went over to the pool. The next thing we knew, he was in the water.
#Person1#: Can he swim?
#Person2#: No, he can't. We told him to stay in the shallow part of the pool, but he slipped into the deep part of the pool by accident.
#Person1#: That's horrible. Did anyone notice what was happening?
#Person2#: Yes, lucklily Henry was nearby and immediately realized that he was drowning. Henry has taken some swimming lessons. So he knew right away that my son was in danger.
#Person1#: You must have been in shock when you found out what was happening.
#Person2#: Yes, we were so frightened. We'd originally planned to swim there for an hour, but after that, we left in a hurry.
