Ever Have the Feeling Your Being Watched?

I was out front, and it was very dark. I was shooting some pictures in the dark. I could see that the girls window was open, and had a feeling someone was peeking out. So I said "girls are you in bed." There was about a 3 second pause, and a some very quite pitter patter, and then came the reply "yeeeesssss." So I waited a couple of minutes pointed my camera at the window, and bang GUILTY! Two little heads in the bottom corner of the window. Click on the picture to enlarge the photo, and you can even see which child is which head. It gave me a good laugh.
