“That's the real trouble with the world, too many people grow up. They forget. They don't remember what it's like to be twelve years old. They patronize; they treat children as inferiors. I won't do that. I'll temper a story, yes. But I won't play down, and I won't patronize.”

From Walt Disney World: Then, Now, & Forever: Too many people grow up. That's the real trouble with the world, too many people grow up. They forget. They don't remember what it's like to be 12 years old. They patronize, they treat children as inferiors. Well, I won't do that. I won't do that. I'll temper a story, yes. But I won't play down, and I won't patronize.
