Wake Up!
We tried talking, yelling, and otherwise banging on the windows. But Catherine was sooooo sleepy that her head just nodded up and down like a very flexible bobblehead doll: she ignored us for about five minutes. Tracy and I were laughing, it was so hilarious. Mark finally got her to stay awake.
Catherine tried to open one of the locks, but she couldn't. Finally, she rolled down one of the windows far enough so that Mark could slip his arm inside to unlock the door. We were all quite relieved and went to celebrate with a hero's lunch of scones and sandwiches.
