F: I heard something terrible happen to your son last weekend. ,M: 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. ,F: Can he swim? ,M: 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. ,F: That's horrible. Did anyone notice what was happening? ,M: Yes, luckly Henry was nearby and immediately realized that he was drowning. Henry is taken some swimming lessons. So he knew right away that my son was in danger. ,F: You must have been in shock when you found out what was happening. ,M: Yes, we were so frightened. We'd originally planned to swim there for an hour, but after that, we left in a hurry.
