Three un-set pieces of occasional charms, sometimes just as elusive as those ""inklings (which) come to me in flashes like the stomachs of goldfish"" although in the first two Mr. Gerald also records incidentals with a stylized Dick-and-Jane simplicity (""We talk to her friends. We go to the movies. I walk the dog.""). Time no doubt passes this way but relationships can thereby be diminished. Thus both ""Memories of a Marriage"" and ""Silver Apples"" deal essentially with the loss of love in a gentle fashion -- ""We weep and uselessly pat each other like strangers looking for something we had and lost until there is nothing left but silence. The moment is never completed, it has never ended."" In ""Conventional Wisdom"" the tone is more playful for the most part, beginning with the dismal problems of plumbing, going on to other horrors (""Non-specific Urethritis or Naked Fathers"") and expanding on a few of them in such instances as too-rich girls (or ""When Your Wife Has a Baby by Another Man'), ""the sort of problem (which) does not occur casually"" nor can be taken lightly, or can it? A small book, to be sure, but there are moments -- attractively on the wing.
