Riddle.

One day, when she's old, she'll tell you the answer to the riddle that has been tormenting you for years. I have heard this one before; the words curve like a spider's silky web, they are put on the shelf in the wine cellar before being released to the public If poems beat on the back door, would you think to answer it? Would you know, quickly now, how to explain the ending to every story? Metaphors drop out of the sky like clouds; they land on your doorstep, shaking and shivering in the cold. Will you take them in? They are orphans, you know; they have nowhere else to go.
