Mom's Eyes

Ha! I saw Evan doing something out of the corner of my eye and without looking at him told him to stop. He surprisingly asked me how I knew what he was doing and asked if I had eyes on the side of my head. I answered maybe. Then he said "you better not have them in the back of your head!"
P.S. Evan wasn't doing anything wrong--just a weird habit he's picked up of biting his lips.
