What was Knapp's relationship with William like?

William was also a raging alcoholic. He had promised to quit for years but never did. Once Knapp was sober, they met up to talk. She explains that AA tells her to take everything one day at a time. Knapp would share some of her stories. All William could think was that at least he was not as bad as Knapp had been. William was still encased in denial of his disease.
