Maybe you don't know everything there is to know, man

I appreciate your efforts to act as mediator in the recent conflict between myself and Mrs. Winchelsea. However, there are some things about the latter that should, at the least, touch upon your consideration. Specifically, Winchelsea has played a central role in some rather shocking examples of vandalism. I hope that, with this new knowledge, you will understand that my attack on her was absolutely necessary.
