One steady and reassuring fact of our troubled times is that good fathers still produce good sons. There are exceptions to every rule, of course, but a father who cares will generally produce a good 'un who makes him proud.
As a member of various fight groups and boxing associations, I regularly encounter the sons of former boxers, trainers and managers who speak glowingly of their fathers' achievements in both soft and tough language. In a nice kind of way, it's a bit like going back to school. You don't dare tell them that your daddy could whip their daddy.
