Vows again. Euterpe understood vows - she was Greek, she had seen people taste the black waters of Styx and speak unbreakable bones - but she couldn't understand a vow of not dating people.
"But..." Euterpe tried to puzzle this out more clearly. "If we both like each other... then if I were to kiss you right it wouldn't be messing with vows. It's not like it would be frivolous." She stood just in front of him now, her voice lowered. "When I kissed you in the kitchen that night it didn't mean anything to me. It would have been a fun night and I was into that, but that was before I started feeling like this. If you kissed me now, it wouldn't be meaningless. Your god would be fine with that, right?"
