Well, at this point I've decided to stop trying, at least for a while. I have not received a reponse to my latest message, which generally means with this person that offense has been taken, and this is despite my best efforts to be clear and non-inflammatory. Rather than continue to try and seek clarification, I will just base my decisions on the best information that I have available and take action accordingly. I risk misinterpreting (at least, the hope is that I am misinterpreting), but I think that I have made more than ample efforts to attempt to resolve, and all I am doing is growing more frustrated. I am, at least in the short term, choosing to disengage.
