My SO and I got into a disagreement because apparently I have a decent vocabulary. This pisses her off because she doesn't understand, "like half the things", I say. She also gets bothered if I correct her when she misspells something. Then she drops the I don't care about her feelings crap. Basically I left it off that I care and that's why I want her to be right, not walking around being ignorant.

I know this'll blow over, but I'm pissed and I'm not going to break frame by blowing up at her, but it's really frustrating. I can't stand when you're trying to help someone and they get annoyed because they were wrong in the first place.
