Thanks Steve and Boat. The dinner is on a weeknight and I would rather just stay in and spend time w the kids because I get up very early for work. I know DB is about GAL and I have done a lot of that (W is even commenting on how much I get out). I don't want to be the sitter every time she's out but in this case I want to be w the kids. So rather than "I already have plans" I'm inclined to say "I'd like to but I can't, I'll stay here w the kids." Thoughts?
