As we sat down to dinner, Tyler cuddled up to me and whispered in my ear. "Grandma, will you teach me how to do that?" When I asked him what it was he wanted me to teach him, he said "see through walls." I explained to him that was something only adults were allowed to know about and that he would have to wait until he grew up. "Well" he said, "will you teach me how to do it then?" And of course I said yes.
