On Tuesday my mom and I very spontaneously (especially for her) booked her a flight to come visit us for the weekend. The kids and I are off school today and tomorrow, and I have Monday off as well.
The kids don't know she's here. Joe picked mom up late last night at the Philly airport. They're still both asleep. The kids are watching Ratatouille*, oblivious to their upcoming surprise.
Pretty soon, mom will wake up. She's not the late-sleeping type. Can't wait until the kids find out she's here. :)
* Wonderful movie. If you haven't seen it, get it. It's out on DVD now.
