What to do?

My four big kids left this morning to go spend the week with my parents. They are SO excited. Me? Well, I'm having a bit of a hard time. You see, my boys have never been away overnight with out us. Jael has for two nights. Once when Anson was born and once with my mom and sister after Shad was born. Before they left I asked Shad what I was going to do with myself while he was gone. He gave me a bit of a "well, duh" look and said, "Clean." I don't think he realizes that with him gone, that won't keep me busy very long.
