I once tried to straighten her out. Every time it was raining, I would take her outside and have her wait in the rain until I said she could come back in.
I did something similar with Calder and Stenvar when they decided to get in a fight over who could have a wooden plate I dropped when I was doing some redecorating after buying Hjerim. That was actually the *second* item they tried to fight over, the first one was valuable so I could see where somebody would want to call dibs if they misunderstood what I was doing and thought I was throwing it away. But a wooden plate? Obviously the two of them were just in a mood to misbehave.
So I made them stand outside on the front stoop for the rest of the evening, in one of those wonderful blustery Windhelm rain/snow squalls. I like to think the guard on patrol came by several times and saw two burly warrior dudes standing outside the Thane's house holding torches aloft, possibly waiting for me to come out and lead them on some big adventure, and asked, "What is it? Dragons?"
And they'd just be hemming and hawing and staring down at their shoes and finally answer, "No we're having a time-out because the boss says we need to stand here a while and think about what we did."
