Julia began getting ready for bed, while William was putting Susannah down.

As she got out of the shower and into her nightie, she could hear him reading to Susannah over the baby speaker they had installed. She leans closer and realizes he is reading from the Periodic Table.

She presses the button, "William, read her something better than that."

"It's important, Julia" he says over the intercom

"She's only 6 weeks old and doesn't understand. Just read a fairytale book from the shelf, please"

"Fine"
