Spy Games?!?

I could not find the children this morning after showering and it was strangely quiet. Dave headed outside to shovel so I went in search of the threesome. They were nowhere to be found. Finally, I noticed an open window in the guest room when I ventured outside. I followed up by finding the guest room locked from the outside (kind of a freaky for our guests!) and no children inside. Looks like they had climbed out the window. Why aren't they somewhere closeby and why aren't they answering?!

Dave yells to me from the front yard to come quick with the camera.







Here's what you do on a snowy Sunday morning when church does not start until 1pm and you happen to be spies: you lock yourself in the guest room and open the window. You build a fort and then a way to get out the window. You climb out the window and travel from the backyard to the front door without being caught and without touching snow. And then you run back to the guest room and go in through the locked door to do it again. Of course. And definitely, you do it without putting clothes on.

And here I was worried...
