When you don’t know…make something up

A mother and her young daughter standing in front of a mixed-species exhibit in the nocturnal Australia building:

“Mommy, what’s that animal?” (Pointing at a hairy-nosed wombat.)

“I don’t know.”

“What’s that one?” (Pointing at a brush-tailed possum near the wombat.)

“It’s a baby of that other one.”

“But why does the little one have a tail and the big one doesn’t?”

“Because their tails fall off as they grow up.”
