Watch your back

The other day, Christopher told me that he wished he could see his back. I asked him why and he simply stated, "because I have never seen it and I want to know what it looks like." I suggested that he look in the mirror. He proceeded to look over his shoulder as though he were looking in a mirror and said, "that would still be kind of hard." I didn't have another answer so I just left it at that and we will wait and see if he brings it up again.
