,begin bold,from The White Knight's Song,end bold,



I'll tell thee everything I can:
There's little to relate.
I saw an aged, aged man,
A-sitting on a gate.

"Who are you, aged man?" I said.
"And how is it you live?"
And his answer trickled through my head,
Like water through a sieve.



(from "The White Knight's Song" by Lewis Carroll)
