Sorry, but this is not a good day. And I'm losing patience and it's P'ing me off that she's so calm.
Look, don't let her turn this back ON YOU. This woman knows you better than anyone else in the world, which means she knows ALL OF YOUR BUTTONS, and trust me, son, SHE'S GOING TO PUSH EVERY DAMNED ONE OF 'EM, starting with the ones she knows always work the best.
Yes, she appears calm. So effing what? Does it really make a difference? "a" you don't know if she's calm on the INSIDE, and "b" even if she is, that says a helluva lot more about her than it does about you. (poor character, that this wouldn't even bother her).
She is strongly into "not going to give him the satisfaction" mode. I suggest you do the same, while making your behind-the-scenes moves.
