It paints a lonely and desperate picture of old age - if this is the general experience (say it ain't so...), it's a bleak story indeed. But then again, our everyman (yes, he is nameless throughout the book) blames his loneliness on being a disloyal husband/father. Perhaps Roth is telling a morality tale, then, which isn't attractive. After all, the protagonist's brother, Howie, who doesn't appear to stray like him, enjoys a rich old life with a loving wife and four doting children.
The most enjoyable bits are his relationship with his brother and memories of their father's jewelry store. It's clever of Roth to set this idyllic time within a jewelry and watch store, jewels representing permanence and watches Time. His father's store is described as an Eden, "a paradise just fifteen feet wide by forty feet deep disguised as a jewelry store", and so the mere passing of time banishes the sons from this Eden.
The old man's lust for women brings to mind a recent film, Venus, with Peter O'Toole as a charming, sexed up geriatric named Maurice. In Venus, old age is similarly described as a lonely time, and Maurice fumbles around for physical pleasure, probably for him the last thing worth living for. The difference between Maurice and Everyman is that we get to see a fuller life in Maurice: in old age, he still enjoys acting, has friends, reads books, etc. Whereas Everyman the book is a succession of anecdotes about death and hospital emergencies.
Nevertheless, the concluding pages are satisfying, what with the matter-of-fact conversation Everyman has with the gravedigger, the final character he meets. Also satisfying is when death finally comes and we are spared any further bleak thoughts on life. I might also add that it is quite a chilling ending to have the moment of death articulated as a horror vacui.
Roth may not agree, but the gravedigger is the true 'everyman' to me, because I suspect people in general do not dwell on death as diligently as this main character does. I suspect most people carry on with their jobs without even thinking about life/death, even though they may face it daily, just like the gravedigger.
