My 4-year-old, A.J., asked if he could have a chameleon someday.

“Um, maybe,” I said.

“Please,” he begged. “A chameleon is an animal, and it changes colors.”

His dad said, “It sure does. And it’s a reptile.”

“I know,” A.J. replied. “Please. I'll take care of it. It’s tiny. I’ll get a tiny little shovel and pick up its tiny little poop!”
