Here's how it went with Caleb (5) and me (42).Me: Hey, Caleb, I have a question for you. Let's say there's a bunch of giraffes, grownup giraffes, some boys and some girls. Do you think those giraffes are different from each other?
Caleb: Yeah, they're different.
Me: Really? How?
Caleb: Their spots, they have different spots. And their necks too! Some are longer than others. Oh, and their personalities.
Me: Hmmm, cool. What about earthworms? Remember those earthworms we dug up last summer? Do you think they're different from each other?
