It has nothing to do with her emotional range, and I'm pretty good at rolling with the punches. Emotional range has nothing to do with common decency. I've interviewed sociopaths with better manners than her. Especially when she's taking pot shots at me and my best friend.
You know me, though, I'm a roll with the punches kind of guy. You're friends with her, so the only reason things haven't gotten loud is because you see something in her worth knowing. So, I'm willing to give her the benefit of the doubt. But I sure as hell am not gonna sit around and pretend that it's okay for her to do things like that.
