I definitely have been here before....as we have established GH, your W and mine could be sisters (or even the same person for all we know). I guess the point here is that even if she does attack, you still have gotten a point across and then by following up with some of the statements that OT has been so kind to provide, you may come away losing the battle, but ultimately winning the war. Think about it, I don't know about you, but in the past, I would respond to her denials by upping the ante and getting defensive and accusatory in my response. Always wanting to be right. If this is you, then responding as OT had suggested would be a HUGE 180 on your part and would get you points in the long run. At the very least, you didn't remain idly by.
