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. I'm sure we can both agree that she needs more sleep than this, and this is not what's best for her. Please make sure in the future if you're going to be out past midnight that there is another adult at home to supervise the kids, or let me know and I'll take them or make arrangements for them at my place.
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.
