Remember POJA and your communicative skills! Get his input on how to solve the problem before you make your proposal.

He doesn't think her sending one TM is that big of a deal. I do. I can't make him see my POV ... I can try to influence him, but that would only work if he wants to be influenced.

Put yourself in his shoes ... how would you want this subject brought up to avoid LBs and work toward POJA?
