And this is how I found Elizabeth sleeping on the air mattress when it was her turn:

...really sunken in. It's kind of hard to tell from this picture, but she was practically touching the ground. Somehow (I don't know how it could happen - it's not like I have four monkeys jumping on the bed each time the air mattress rolls out.) the air mattress got a hole in it, and it deflates while you're sleeping on it. I've looked and looked, but I can't find the hole to patch it up.
*On a side note, I really need to audition Elizabeth's room for Clean Sweep or something. She is our collector/hoarder. I call her the Queen of Crap because of all of her, shall I say, treasures.
