One sock off, and one sock on

Things I don't know:

(a) where George's other sock has gone
(b) how his feet don't hurt, walking on those stones
(c) why he smiles like this.

Life got even more mysterious, when he asked me:

"Dad? Are you a happy dad?"
"Yes, George - I am. Are you a happy boy?"
"No."
"No? Why's that?"
"Acksherley, I am. I am a happy George."

Glad we got that sorted out.
