My three sons

I do have three. I hereby shout it to the world in the one place I can do so without answering a lot of questions. I lined up pictures of the three of them on my computer desktop and looked at how alike and different they are. Similarities, definitely, but no clones among them, although Nathan and baby 4 do resemble each other more than baby 3 resembles either of the other two. Anyway, just reaffirming an invisible bit of reality.
