It was our first weekend away without kids in a very, very long time and it was wonderful.
It helps to have some pretty terrific in-laws willing to entertain your kids while you're away.
So terrific in fact, that your kids, who you've missed terribly, even while having a blast, couldn't care less that you're there to pick them up and would in fact like to stay a little while longer please. (They did let me know they missed me when they asked to skip music class this morning because they hadn't seen me in like 3 whole days.)
In case you were wondering yes, those that wanted to did in fact skip class, spending some time to reconnect instead.
