I wouldn't worry about it. She's done soon anyway. Who cares if she gets angry and pulls out early?? You need time to feel like a human being, do you think she would think twice about calling her child in sick if she wanted to do something??

I know what it's like to not see much of your husband, if I was presented with the opportunity to get away with him for a few days I would run for it! I would tell the parents I was closed. Period. If anyone came back at me with a sob story, I would simply tell them "I will NOT be here to answer my door".
