To Rey it makes enough sense. She hasn't been around many children, but she knows they're rowdy, noisy, and not very good at being conspicuous.

"Don't... really have a 'people'." Rey casts a sidelong gaze, chewing the inside of her cheek. It's sad but it's also true -- she doesn't have a tribe or community to call her own. And the few she could, she doesn't want to burden herself upon. "But, have heard a few lullabies in the last. Songs. Stuff like that."
