He doesn't even kiss the kids goodbye when he leaves - what kind of father does that?
That might be a product of his own upbringing.
He's probably hurt, too, although being a jack about it instead of changing, which might make him want to run away from the trips and the stress of what he caused. Don't you wish you could grab him by the arms, drag him to his room for a timeout and then have him become the man he could be??! If it were so easy, I think I'd do that to myself!
