Alan Alexander Milne - Brownie

In a corner of the bedroom is a great big curtain,
Someone lives behind it, but I don't know who;
I think it is a Brownie, but I'm not quite certain.
(Nanny isn't certain, too.)

I looked behind the curtain, but he went so quickly -
Brownies never wait to say, "How do you do?"
They wriggle off at once because they're all so tickly
(Nanny says they're tickly too.)

Alan Alexander Milne
