Stone

"If you don't believe me," says the stone
"just ask the leaf, it will tell you the same.
Ask a drop of water, it will say what the leaf has said.
And, finally, ask a hair from your own head.
I am bursting with laughter, yes, laughter, vast laughter,
although I don't know how to laugh."

from Conversation with a Stone by Wisława Szymborska
