This is one of those indefinable books that may catch on and sell, year in, year out. There's nothing very profound in the analysis of the basis of real friendship, but it is gracefully and charmingly done; with plenty of human touches, some delightful and pointed anecdotes -- and some well-placed guideposts. Shared experiences, -- whether culinary tastes in common, humor, enthusiasms or tantrums handled just so; appreciation of places, rescues from predicaments -- all aptly illustrated. The perfect after-a-week-end guest gift to the hostess whose friendship is valued.
