I remember when the Hamilton family were living in New York state and they came to visit us one weekend when we were living in Indian Mills, New Jersey.  Sylvia and I were former roomies in college and after college and we were anxious to visit and get to know one another's children.  Mark was around 3 or 4 and what I remember most about him on that visit is that he did not drink water - ever!  The only way he ever got his water was by eating popsicles.  Sylvia came with the popsicles in hand to go in my freezer. Smart kid!!
