F: Hey, we should watch the kids more carefully when there in the pool. Did you ever hear about secondary drowning? ,M: No, never heard of it. Is that like when you get water up your nose? ,F: Don't joke about it! I learned it from the Internet. Some children die each year because they fall into a pool or a lake, but they didn't drown right away. Someone pulled them out of the water and they seemed OK for the first day. But a lot of water got into their lungs, and the next day, they died. ,M: It happens very rarely. We have to let the kids have fun. We can't protect them too much.
