It’s not really a huge fight, but we’re not talking to each other, which actually means that I’m not talking to him. He probably hasn’t even noticed because he’s pretty oblivious to other people’s feelings these days, and I don’t want to upset him by telling him, “Hey, Dad, in case you hadn’t noticed, we’re having a fight, okay?” He’s got a lot on his mind and I don’t want to make him even more depressed.
