From George’s Marvelous Medicine:
“You know what’s the matter with you?” the old woman said, staring over the rim of the teacup with those bright wicked little eyes. “You’re growing up too fast. Boys who grow too fast become stupid and lazy.”
“But I can’t help it if I’m growing fast, Grandma.” George said.
“Of course you can,” she snapped. “Growing’s a nasty, childish habit.”

And she should know – she still has all of her nasty, childish habits … 😉
