re:You did not need to, it is implied in what you said.
I quote: "And she made unprovoked nasty personal comments..."
If you are upset by what she said, then it implies that you would want her to be better and perhaps as good as you. If you consider yourself as better than she is, then it implies that you would not stoop to such a low level as she has.
The truth of course is that YOU have "made unprovoked nasty personal comments" to many people over several years and therefore are FAR WORSE than Lindy.
