Encounter with a young insect enthusiast

“Did you see some of those caterpillars?”
“I don’t know. What kind are they?”
“They’re green and about this long,” he demonstrates with his fingers- about an inch and a half, “and they have horns that if you poke them they go in, and they smell kind of weird.”
“Nope. I didn’t see any of those.”
“Darn. They’re awesome.”
