It definitely feels odd, to Charlie, to be talking of work while Hermione shops for her wedding dress. They seem like two topics of polar opposites, both important, but for entirely different reasons. But Hermione seems keen to discuss the topic, so Charlie doesn't feel guilty at disrupting her routine.

"What is the Lamplight?" Charlie asks, intrigued by the name and the fact that Hermione herself runs it. It sounds like it has to do with magic, which appeals to Charlie greatly. "And I suppose you're right, about the animals bit. I'll have to look into that, perhaps."
