The simplest exchange turns into a lively discussion of opposing viewpoints. There`s no problem here because none of you take your differences personally. It`s the best time to be in a relationship with these people. Minor flaws are soon identified and ironed out. Schedules are vetted and overhauled, and at least one or two foresighted individuals are lining up the resources needed in the foreseeable future. A close collaboration is definitely called for.
