“Tiffany took a deep breath. This was about words and she knew about words “Here is a story to believe,” she said. “Once we were blobs in the sea, and then fishes, and then lizards and rats and then monkeys, and hundreds of things in between. This hand was once a fin, this hand once had claws! In my human mouth I have the pointy teeeth wolf and the chiseled teeth of a rabbit and the grinding teeth of a cow! Our blood is as salty as the seas we used to live in! When we’re frightened the hair on our skin stands up just like it did when we had fur. We are history! Everything we’ve been on the to becoming us, we still are. Would you like to hear the rest of the story?”
Tell us, said the hiver.
“I’m made up of the memories of my parents and grandparents, all my ancestors. They’re in the way I look, in the colour of my hair. And I’m made up of everyone I’ve ever met who’s changed the way I think. So who is ‘me’?”
The piece that just told us that story, said the hiver. The piece that’s truly you.”
A Hat Full of Sky, Terry Pratchett
