What is the author's tone in the memoir, The Tender Bar?

The overall tone of the story is one of hope, despite the years of despair and tragedy the author and his family endured. Moehringer and his mother Dorothy endured years of poverty. Unable to live on Dorothy's limited income and without the benefit of any child support, they were often forced to live with Dorothy's parents. That house was chaotic and unstable, but it provided a level of security from the outside world and family members for companionship. Moehringer then went through years of struggles as an adult, first in college and then in trying to break in as a reporter. His problems were escalated by the hours he spent drinking, gambling, and in unhealthy relationships. The bright spot was the genuine friendships he formed during his hours at Publicans. An important part of the tone is that Moehringer wrote the story as a memoir, making it clear to the reader that he did become successful as an adult.
