Jenna While my own choice of words would be very different from yours, I feel like this is an excellent example of respectful disagreement. You, Sasha and I have very different views on the issue, so we approach the subject matter with very different value systems, experiences and perspectives in mind. But instead of focussing on the differences in our premises, this post highlights the commonalities of the conclusion: That the best-case result is that this arrangement buys the two time to resolve their differences and figure out a way forward (with the worst case being that it drives them apart further). I think it is a great idea to have Susan be the one to do the talking with Jane, so that Jane has someone who is closer to being her peer than Monica's.
Jenna I have an enormous advantage over Monica in that I have 2 girls who love and respect me, so while initially difficult in selling them on advantages of wearing a belt, I ultimately succeeded in getting them to understand their value and importance.
And I have to appreciate you for taking the effort to work with them, rather than against them, on this matter. For, at least as far as I can tell as a casual observer, navigating this dangerous situation of a power imbalance and making sure that the arrangement you have is upheld by mutual respect, not coercion.
