Peter was expecting a heart-to-heart conversation with his dying father. He wanted stories about life and love. He wanted a meaningful connection.
He’s just about ready to give up.
Dad was having none of that sentimental nonsense. He just kept messing with Peter like he always does. Like he’s not going to die at any moment.
But death doesn’t wait for anyone to be ready. Death doesn’t wait for the perfect moment, after the perfect words. Perhaps dad just wanted to die the way he lived: being a dickhead to Peter.
