As if I had any right, I got up and marched into the middle of the room, physically separating the two, still mid-yell.
"This is stupid and has gone on for way too long," I yelled to both of them. "You're getting nothing done yelling at each other, so find a place to sit down and listen to what I have to say for a bit." Taylor opened her mouth to protest so I quickly added, "Don't argue, just do it!"
That seems to have done it. I felt good, like I was Ben Manibag when I said that or something, though realistically speaking I probably looked more like Napoleon...
