If I'm up, everyone else should be

I thought this description of a young child waking up, in the novel Independent People by Halldor Laxness, was great:

Were they afraid to wake up, or what? He began tapping quietly with his fingernails on the sloping roof, a thing he could never, in spite of threats, restrain himself from doing when he felt that the morning was being prolonged too far. When this had no effect he began to squeak, first like a little mouse, then sharper and higher, like the squeal of the dog when you tread on its tail, and finally higher still, like a land wind shrieking through the open door.

"Now then, that's enough of your nonsense."

It was his grandmother. The boy had succeeded, then. (pg. 147-148)
