Yes, Bworl, it was cold. And in the end, things ended up cordial and, maybe it wasn't the best DBing technique, but I hugged her and gave her a kiss on the cheek. To her credit, she did want me to pick up the papers and offered that option; so, you're right, delaying getting them was only making her angry.
On the other hand, I told her that I would get them, but I wanted to sit down and talk to her first. I think her getting me the papers before the talk was important to her to help insulate herself from anything I had to say. The deed was done, and the faster one gets something they know is wrong done, the easier.
In the end, though, I do wish she hadn't selected one of our favorite restaurants to do it.
