"One more thing, hope to get a response before I pick up D3 in 3 hours. I am sure that my W is going to try to talk again about the weekend trying to get me to switch days. I think that I will just firmly state that I will pick up D3 on Saturday. I am not going to say Sorry because I didn't do anything. We COULD all go, but that is not going to happen. Should have told my that she must not want to go that bad because we could all go...lol"

That is the route I would take. Although I'm currently fluctuating between agreeing/cooperating and taking a stand.

For me, it comes down to N.U.T.S. If its a NUT, I won't compromise or cooperate. Anything else is small stuff.
