When reading a book, I usually find myself coming back to what I call the "Three Cs" - Clarity (how well it is written), Consistency (do the characters behave in character), and Cohesiveness (does the whole thing stick together). I have found over a lifetime of reading (and I am past the half-century mark, thank you) that these measures pretty much apply to any book, in any genre.
More than that, Elinor Lipman takes the everyday and makes it ... more than that. Events do not need to be extraordinary to make them meaningful. I think the present generation has lost sight of the simple fact that the simple things and the basic emotions that go with them are important in their own right. Everything does not have to be an adrenaline pumping heart-pounding YouTube event to be important in a person's life. To expect otherwise is, I believe, missing the point of life entirely.
Thank you, Ms. Lipman, for writing about what it is really like to live life, and to be aware you are living it.
