Beautiful children. Congratulations to their mother! Great photo, too. Wonderful color coordination. The reason that I asked, as beautiful as your daughter is ... is because of your son's hair style. I know that today parents put styling gel on their kid's hair to get that look. But, when I was a kid in the early fifties, that was the look that mothers would attempt to do away with with butch wax and such. You see, that look came about originally by the very natural look that results from young boys sleeping on their head on one side and then turning over with the intense application of head pressure on the other side of the head for the rest of the night. The result of course, is the "wedge head". I had it, and your son has it. And mothers around the world have now institutionalized it. When the time comes that your son is ready, not before, be sure and induct him into the cult of the Wedge Heads. It is almost as good as being a Longhorn, but not quite.
