Our voices didn't matter. It didn't matter how we voted.
My suspicion is that she feels that way because she lost. A wild guess, but I think she's so selfish that she can't imagine other people's voice/desires mattering as much as her own personal wishes; their votes shouldn't count like her's does.
Fair. But I think the reason behind that feeling is different between the two of you. One is internal, the other is systemic. Though I guess if you were to ask her, she'd say the same thing in reverse.
