"That's okay then." Katie takes the stethoscope and goes to listen to the fridge.
Virginia shifts so she can see into the kitchen from where she's sitting, and pays attention to Katie while she does her math homework. Rather more attention to Katie than to the math homework, in fact.
Katie listens to the fridge, and the microwave, and then she lets the microwave go empty for five seconds and listens to it while it does that, and then she listens to the kitchen window.
Virginia is confused.
Eventually Katie is bored of the stethoscope. She puts it back in its box and goes to sit by the window and look out at the sun.
"Please don't look right at the sun," says Virginia. "Doing that can hurt people's eyes, and you can't always tell right away how hurt they are."
"But Giiiina, I like the sun," says Katie, turning to look at Gina. "It's bright and it's pretty."
"You can look at other bright pretty things," she says. "But not this one, because it might hurt you."
"It might still be doing bad things to your eyes," says Virginia. "The only way to know for sure that it isn't would be to keep doing it and see if you go blind. I'm not going to let you do that, because I don't want you to go blind."
"It might be like thumping," she says. "But I'm not sure it's like thumping. And I don't know a safe way to find out. Staring at the sun is not a safe way to find out."
Katie picks out a book she hasn't looked at before, and hoists herself up onto the couch where she was previously sitting, and reads.
Katie pages very slowly through the book, but she does appear to be really reading this omnibus collection of Sherlock Holmes stories.
As long as she's having some approximation of fun, Gina decides not to make a fuss.
