re: Anyone else not on speaking terms with a parent?

One of the saddest things I heard in my life was last year. My wife nephew just lost his mom, so she asked could he ride with us to the spring game to get his mind off it some. We’re leaving town and I see a guy that worked for me once walking down the road. I said “Yeah, there old Mike. He could be a good dude if he could get right”. The nephew said “Yeah, that’s my dad”. I didn’t put two and two together at that moment. We’re at the game and I asked my wife about it. That really was his biological father. The guy just wonders house to house, walking by his son’s house daily. So I asked him about it later that day. He just said “It is what it is man. I’ve tried to speak to him and he just ignores me”. Sad…
