It wasn't so much that it went over her head-it didn't-it just happened that what he told her was a lot to process.
She just listened a moment, thinking a little longer after he spoke.
"Oooh." Well, she had read about stranger things indeed, and she could see that her own daddy would be disgusted about such things-then again, when wasn't he about anything that didn't lead to him getting more money. "Alright."
So he was attracted to another man..maybe like how Frodo was friends with Samwise Gamgee-though the latter was married at the end of the book series: she could understand that.
Really though, she didn't see how it mattered. It was like he said: attraction was attraction.
Besides, if they were in their own room, she hardly saw how it mattered-it was rather like her own parents at home.
