Speaking to me in a patronizing tone of voice (such as you might use when you've just brought someone home from a mental institution and they're speaking in gibberish and making no sense)
Snapping at me and biting my head off over something trivial
Speaking to me in that sighing, weary "you're such a PITA" tone of voice, and then denying he's doing that when I call him on it
Telling me I'm being too sensitive
Not apologizing... not being willing to own that he did something mean. Or the back-a$$ed apology: "I'm sorry you feel that way."
I liked a bunch of Corri's, too-- especially me making excuses because "at least they're trying" when you're really not getting results.
