This morning, upon coming downstairs and finding the kids not only awake, but playing Wii....
Mommy: "How long have you two been up?"
Miss M: "About an inch and a half..."
A) It's Saturday and B) that was funny, so I just didn't fuss about the whole playing-wii-without-actual-permission thing. They have been waiting for the weekend this week (they usually don't ask "When's the next no-school day?" It's been a long, busy week...), so I'll let them play just a bit longer.
