Carefully, Lynn starts showing her the basics of how to swim.
And Astrid carefully swims. She is not unusually gifted at it, but she manages the dog paddle.
That's perfectly all right! More graceful forms of swimming will come with time and practice. Lynn praises her successes and corrects technique when necessary.
But if she weighs as much as a duck, she's a witch. Har, har.
"Let's see, do you have any feathers?" Lynn pretends to check. "I can't find any, can you find any?"
"Oh, dear! What about a bill, do you have a bill? Hmmmmm, no, that looks like a nose to me." Just to prove her point, Lynn pokes it.
She spends much of her time around high schoolers who occasionally contemplate things they'll be able to do on reaching the age of majority.
"I am heartbroken," says Lynn, gravely. "What happened to your wings, dear duckling?"
"Bad people! Why, I'd argue that they're worse than that. They are," she lowers her voice conspiratorially, "supremely aviophobic. And they're not even the ones flying!"
"Aviophobia is the fear of flight. Usually it's when a person gets on a plane and goes flying, but I stretched the terminology a smidgen to mean fear of flight in general."
