What is the meaning of "They don't let you" in "The House At Pooh Corner"?

Question

This is from The House At Pooh Corner by A. A. Milne:

Then, suddenly again, Christopher Robin, who was Still looking at the world with his chin in his hands, called out

“Pooh!”

"Yes?" said Pooh.

"When I'm--when-- Pooh!"

"Yes, Christopher Robin?"

"I'm not going to do Nothing any more."

"Never again?"

"Well, not so much. They don't let you."

Pooh waited for him to go on, but he was silent again.

What is the meaning of "They don't let you"? I think that "They don't let me (do nothing)" would make sense. Who is "you"? Pooh? What is the word after "let you"?

Answer 1

What they don't let you means here is they don't let you [do nothing].

Here, they is the generic they, meaning people in general (including many of the adults that Christopher Robin interacts with).

And you is the generic you, which also means people in general, although in this case it means a different set of people (which includes Christopher Robin).
