In theory, I agree with you 100%. All I can say is that she is extremely irrational and that type of approach will mean little to nothing to her other than her viewing it as an attack. Could I view her words as an attack? I can and do. Part of me doesn't want to stoop to her level and the instances I have (politely even) pointed out that she had issues as well, it never ends up well. I find that when I am the "bigger" person and let things go in one ear and out the other (after they ruin a few hours or days of my life, unfortunately) and I respond with a civil attitude, I tend to feel a lot better about how I handled it.
