What is the author's tone in the memoir, About Alice?

The tone of the novel is upbeat despite the sad overtones. Trillin talks about Alice as if she were in the next room, describing her character, as well as their marriage, as though it were a work in progress. Trillin rarely mentions Alice's death and when he discusses her illness, he spends little time on the unpleasantness of the situation and more on Alice's optimistic view of the entire situation. The book is about Alice, about her views of the world, her behaviors, and her childhood. The book gives the impression it was designed in order to describe the indescribable and to explain a perfect marriage that ended much too soon.
