Have you talked to her about it? Mine were both the same way. They both sort of still are.
And honestly, I made mistakes in both my tone and actual words said that cause(d) more tears that I ever thought possible. But once I talk to them like a rational adult about my meaning, they both understood my point of view and why I said what I said even though it hurt their feelings.
I am guessing that was when they were around 8 or 9 years old. I still do it today occassionally. My oldest is studying for a pretty big thing and she got a crap score on her practice test and my casual "you are not working smart enough if you are not improving" went over like a brick to her head. Tears and sobs. Fuck. Once she took a breath, and i explained that it wasn't a criticism of her personally, but of her actions, it made more sense. Not sure if her behavior will change, but I said my piece and it is on her now.
Sometimes, I think that Dad mentality is always going to cause friction. Men think differently, which is why our species survived. ;)
