Ma cherie amie und meine freuden,
Pardon my French and German spelling, please!
Both of you, my dear friends, have been doing an excellent job and working hard to help Wikipedia. I don't think either of you has done anything wrong about the Mediation discussion boards.
However abrupt or rough the request may have been to hand over control of the Mediation board, it's nonetheless a reasonable request.
Sometimes misunderstandings arise, due to language nuances not being well understood -- or due to quick vs. slow ways of doing things, or "intrusive" vs. "collaborative".
Let's put this in the past, shall we?
Being the first to apologize doesn't bring any shame down upon a party to a conflict. Rather it shows who's "the bigger man", the one who cares the most about the relationship. It only raises everyone's opinion of you! :-)
