This is a draft of what I'm planning on sending to W later today. Maybe I'll send it in the afternoon, while W is still at seminar, so she can discuss this at the seminar if there is an opportunity.

"Hey,
I found out last night after you picked D13 up (I wish I had known you had planned to pick her up), that they missed out on gf's D14's b-day party.
Just thinking how the weekend could have been planned different had I known things that affected the kids.
D13 was irritable yesterday and I finally found out on our way back from the city that she was tired. I found out it was because she had gone to bed at 5am. No big deal, but it was just sad because being tired affected our time together, which could have been better.
Had I known about gf's D14's b-day party, we could have arranged for the kids to be here either Friday or Saturday, and then they could have went with you to gf's for the evening on Sunday.
Hopefully we can work this stuff out better in the future.
My Name"

Actually, I might send it late morning. Give her a chance to digest it while she's processing the information from the seminar...
