A lot of it just has to do with the fact that I have a rich emotional life and communicate that quite well. She is smart and educated but she simply doesn't have the same kind of complex interior life I do; from a feelings, imagination, and willpower standpoint.
That isn't a flaw, but it kinda leads to interactions where I'm full of feelings and energy and she has rather swallow emotions and doesn't get that excited or passionate about anything and doesn't really have the same kind of engagement level with life I do. She very much, in the normal course of things, just goes to work, does her taxes, does her chores and goes to bed without feeling anything intense or being interested in anything all day.
Once again, not a flaw, but to a human pogo stick like me I have a hard time with that level of distance from life experience sometimes.
