Owl's House?

"Owl lived at The Chestnuts, and old-world residence of great charm, which was grander than anybody else's, or seemed so to Bear, because it had both a knocker and a bell-pull. Underneath the knocker there was a notice which said:

PLES RING IF AN RNSER IS REQIRD.

Underneath the bell-pull there was a notice which said:

PLEZ CNOKE IF AN RNSR IS NOT REQID.

These notices had been written by Christopher Robin, who was the only one in the forest who could spell; for Owl, wise though he was in many ways, able to read and write and spell his own name WOL, yet somehow went all to pieces over delicate words like MEASLES and BUTTEREDTOAST."
