Eventually, they're interrupted by John's mother entering the room. "Okay, boys and girls, it's almost..." She pauses, taking in the scene in front of her. "...I see. And you're doing advanced math." She peers over at the notebook to confirm. "Brian said, but I could hardly believe it. Treat her right, John, she's a keeper."
John sighs. "Did you need anything, Mom?" he asks.
"Oh! Yes! Supper is almost ready, so finish up what you're doing and go wash up. And use soap! You know," she says, turning to Rosy, "for the longest time, he would just wet and dry his hands before supper, as though that would keep the germs away. Silly boy."
"I was ten, Mom," he says, embarrassed. He admittedly still doesn't fully see the point of washing his hands before eating, he's using a knife and fork after all, and it feels like a waste of time, but, well, if it makes mom happy. But all of that pales in comparison to the fact that mom is telling his girlfriend about his hand-washing habits. "She won't stop bringing that up," he says to Rosy. "It's been a long time since then."
