There are still interesting, funny moments. Once, I had done something that angered him. He gave me the third degree, yelling at me. I started chuckling. He stopped, and angrily asked why I was laughing. I replied he hadn't yelled at me for 20 years, and it felt oddly good and familiar to have him yelling at me. It was good to have my old man back.
Of course, that took all the steam out of his anger, and he soon slipped back into the mist.
