Another much-in-little with a complementary thesis similar to the conclusion of If It Weren't For You (1966, 509, J-169) by the same team. John and his friend split their differences—one can't spell, the other can't multiply; share their assets—a mother who cooks better, a father who tells better jokes; and keep each other's secrets—fear of the dark, fear of cats, liking one girl or another. They also know "what's in each other's refrigerator, which steps creak on each other's stairs, and how to get into each other's house if the door is locked." It's a slightly off-center approach to the give-and-take of best-friendship, aptly drawn out by Ben Schechter who has few equals for glowering determination or the sidelong smile.
