Personally, I've always had a voracious appetite for knowledge. So when I am personally confident about a topic, I forget that others may not really want my input.
Amen to that... I found myself doing this even last night. W shared a story of her supervisor who told her to be careful about what she posts to Facebook regarding the doctors she works with. That she could get in trouble for that. I happened to have actually read the NLRB's decision regarding Facebook posting and employment actions and went on a little dissertation about how that's BS and actually not at all what NLRB decided. Then I realized I was just a) showing off and b) not listening - instead I was solving so I apologized, backed off and listened. I also added in that while the law may say one thing, getting fired and having to fight it would really be not so much fun.
I have noticed that I too get the condescension thing due to size and due to vocabulary. I have a very big vocab. I don't like to use three or four words where one word will suffice.
My W often doesn't know the word I use and this makes her feel dumb and small. And instead of asking for the definition she gets mad and stops talking to me; then accuses me of using those words to embarrass her. This is a big change from early in our R, when she would actually write them down so she could look them up. Not sure when that changed, but I probably should've paid attention...
