I have been living with a deaf person for a long time now so I think more about hearing and what is not being heard on a regular basis. Every once in a while though, I realize that I am not thinking about what can and cannot be heard.
We are having a rainstorm and the window is open so you can hear the sound of the rain falling on the wood of the back deck. There are items the kids need to put away by the window so in an effort to motivate them, I said, "Hey, who wants to clean up by the window and then we can set up sleeping bags and fall asleep listening to the rain?"
Chance piped in with, "Um, that won't help me. I can't hear rain while I sleep."
Then Chance's little brother chimed in with, "Ya, I won't be able to hear it either."
Apparently if you have deaf children, being able to listen to the rain fall while you sleep is not a good motivation.
