Not meaning to add to the guilt trip, but standing on the parade square seeing your family there looking on and beaming away really did make it something special. He has spent weeks bashing the square having it drilled into him that he does not want to let he guests down with sloppy drill etc, so being there will be all the more important to him. Besides, after the parade, everyone around him will be rushing to the family and friends, don’t leave him there on his own!
