All stories have a curious and even dangerous power. They are manifestations of truth -- yours and mine. And truth is all at once the most wonderful yet terrifying thing in the world, which makes it nearly impossible to handle. It is such a great responsibility that it's best not to tell a story at all unless you know you can do it right. You must be very careful, or without knowing it you can change the world.

I tell the story to you now, but in each telling the story itself changes a little, changes direction, and that in turn changes you and me. So be very careful not only in how you repeat it but in how you remember it, goslings. More often than you realize it, the world is shaped by two things -- stories told and the memories they leave behind.

The world is shaped by two things — stories told and the memories they leave behind.

Every story needs to be worth telling.
