“"Aren't there any grownups at all?"
"I don't think so."
The fair boy said this solemnly; but then the delight of a realized ambition overcame him. In the middle of the scar he stood on his head and grinned at the reversed fat boy.
"No grownups!"”

“One of the most obvious facts about grown-ups, to a child, is that they have forgotten what it is like to be a child. The child has not yet had the chance to know what it is like to be a grownup; he believes, even, that being a grownup is a mistake he will never make—when he grows up he will keep on being a child, a big child with power. So the child and grownup live in mutual love, misunderstanding, and distaste. Children shout and play and cry and want candy; grownups say Ssh! and work and scold and want steak. There is no disputing tastes as contradictory as these. It is not just Mowgli who was raised by a couple of wolves; any child is raised by a couple of grownups. Father and Mother may be nearer and dearer than anyone will ever be again—still, they are members of a different species. God is, I suppose, what our parents were; certainly the ogre of the stories is so huge, so powerful, and so stupid because that is the way a grownup looks to a child.
Grownups forget or cannot believe that they seem even more unreasonable to children than children seem to them.”

“A book floated down the Amper River.
A boy jumped in, caught up to it, and held
it in his right hand. He grinned. He stood

“How about a kiss, Saumensch?” he said.”

“We thought we were running away from the grownups, and now we are the grownups.”

“Nico realized he was still leaning against Will. He pushed him away and stood on his own two feet.
‘I’ll do what I need to.’
Will rolled his eyes. ‘Fine, Death Boy. If you want to get yourself killed –’
‘Do not call me Death Boy!”

“Eddie discovered one of his childhood's great truths. Grownups are the real monsters, he thought.”

“Jamie shook his head at me admiringly. “And here I thought I married you because ye had a fair face and a fine fat arse. To think you’ve a brain as well!” He neatly dodged the blow I aimed at his ear, and grinned at me.”

“Dave couldn't remember the last time a grownup had apologized to him.”

“I think if you left grownups to do what they really actually wanted most in the world to do, every single one of them would lie down and take a nap for the rest of their life. I know this because that's what every grownup does as soon as they're alone.”

“Kaoru: Grownups are so tiresome. They fake their smiles all day long and they try to force us to do the same. It's no fun at all.”
