Because she already laid out her position. Why does she need to participate in an optional meeting that you kept stressing was no longer optional?
In fact, what really disturbs me is that Ms. Daly specifically asked you this: “I want evidence. I want policy. I want written direction. I want something official that compels me to participate in a meeting that I'm not comfortable with.”
You agreed that you would provide that, and in fact you didn't. Why didn't you provide policy?
