“Why does the water get up such a noise when it’s going downhill?”
“It’s roaring,” said the first little boy.
“Is it? Why?”
“Because, it’s pretending to be monster. It finally escaped from under the bed and now it’s busy making a canyon,” that first boy answered.
“It’s just shouting. I like to shout when when I’m on a roller coaster going downhill,” suggested a second boy.
“It is shouting,” said a third, “But not for fun. It’s shouting at us to get out of the way. My mom says fast water is dangerous.”
“Get out of my way, I’M MAKING A CANYON!” the first boy shouted, leaping to his feet and brandishing a twig.
