The city boy goes to countryside to visit his uncle. After the sun goes down, the boy hears strange, another-world howling. He gets frightened and runs to his uncle. "Uncle, uncle, there are werewolves!"
"That's rubbish, boy, ain't no such thing".
"'Then, there must be man-eating wolves".
"No, we haven't got those buddies, either."
"What is this sound, then?" the boy asks.
"They are coyotes".
"Coyotes? What are those?"
"They look a lot like dogs. In fact, ya can consider them a kind of dog."
The boy wants to find out more: "Why are they making that frightening noise?"
"See, nephew, we ain't got many trees around here. We got cactuses!"
