I do not have any children and I very much doubt that I ever shall. To be honest it's not really that big a deal to me. Except, sometimes, I wonder what might life might have been if things had gone just a slightly different way. There was a time, nearly half my life ago, when having children wasn't entirely out of the question and every once in a while I wonder who they might have been.
