Guilt vs. vineyard

Grandma is coming to pick up the girls so that they can eat junk food, stay up way too late, watch tv nonstop, *spend the night*, and revel in grandchildness....meanwhile, Marvin and I are going to a winery and are going to a fancy restaurant! I don't know what I am going to wear. I have mom clothes and professional clothes, but no hot date clothes. I need to rectify this situation! When I think about not having kids around for a 24-hour period, I get a little butterfly action in my tummy. But then, like right now, I'm watching them play and I think that they're my best inventions, and I feel like a turd for looking forward to being alone. Dear brain, why the double-edged sword?????
