The road What do they do at the waterfall? Do you think this is a wide or foolish act? Why?

The boy and the father call to each other from each side of the waterfall as if they are tourists. Then they take their clothes off and go swimming. I think this is one of the few moments of respite that the boy and the man have in this book. The world has ended and if they can grab a special moment, they should take it.
