I'm a little late here, but sometimes work just gets so intrusive. Sheesh.
Anyway, re. your convo:
Quote: W: It's like me saying, "say you're sorry" and you say "sorry." H: No, it would only be like that if you had said, "I did all the planning for St. Louis and wish your would thank me," after which I said, "thank you." I'm truly appreciative that you undertook the planning of the trip. Why can't you just accept my thanks easily? W: Well, thanks for pointing out my shortcomings.
I think you did good right up to the last sentence. The truly thankful part was good, but going on with the acceptance question turned it into just what she said: a complaint about her. As I tried to say before but NOP said so much better - you need to be on her team.
