"I can understand your disappointment about not being with the kids earlier on Mother's Day. I'm sure I would have felt the same had the situation been reversed. Please don't hesitate in the future to ask me to change our arrangement for special occasions like this. I will always work with you in good faith. As for Memorial Day, I'm totally fine with you keeping the kids for the weekend. Sounds like you've made nice plans, I hope you all have a good time."
I think it was a good response. Thanks futureunknown! I do think I'm detatching some!
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
