"To be honest, I'm not sure of anything she likes," she admitted, feeling a bit bad about that particular fact. His continued insistence upon something to "track" her emotions, though, bothered her. "I don't know if they have any conflicts in the first place, but it is certainly not my business to impose upon something so private in my own brother's relationship.
"Perhaps it might be easy enough to make something like that...a stone, perhaps, that changes color based upon emotions. The trouble with that, though, is that he would not know what was causing it, only how she might feel. It could be something entirely unrelated to him, even just something that's on her mind. I don't think that would be an accurate representation of what a woman feels regardless of how it worked. It...changes so often anyway," she sighed.
"And I think it's a bit lazy. If you personally have so much trouble understanding women then perhaps you should spend more time listening to them instead of trying to put their emotions on display like they were meant to be an open book in the first place," she told him bitterly, not being shy about listening in on his thoughts this time.
"What do you find calming?" she finally inquired, hoping to find some common thing she might be able to relate to others and make him understand her point.
