The Invention of Happiness, by Brian Aldiss
A recent book by Aldiss, collecting together several dozen short-short stories, of two or three pages each. Actually rather few of them have a beginning, a middle and and end; mostly they are just one or two ideas (sometimes, frustratingly, an idea and a half) explored at the length of a thousand words or so. But they are all unmistakeably in Aldiss's unique voice, more than vignettes, reflections of the world as his characters think it is. Mostly non-sf, at least as far as you can tell in the parameters of the story.
