Welcome to fluther, and that is a fantastic first question. No argument there!
I can’t argue with my spouse of almost 40 years to save my life. We trigger each other immediately and go for the jugular vein. Many atttempts to learn constructive dialog through counseling have done nothing to rememdy this.
I’m much better on the professional front, though there are triggers that I’d still love to wrest control of.
Can you do it without creating further conflict? I’m not very good at this; I’d grade myself a “C” overall. I fail miserably in arguing with the spouse without opening old wounds or defining new battlegrounds.
If an argument begins, do you believe it must conclude before you get up? Depends. If the argument is about something that requires action to move forward, then we must resolve the issue or reach some consensus around resolution. If it’s an argument of opposing viewpoints where there’s little hope of resolution, I tire very quickly.
Do you interrupt while the other party is speaking? I’m generally pretty good at not interrupting unless someone has spoken complete and utter bullshit, at which point I speak right up ;-)
