Joy makes a new connection, too, due to some surreptitious matchmaking by Uncle Max: enter a friendly, eminently promising older schoolmate, also named Max. While this budding relationship is growing into full-scale delirium, Joy returns the favor by encouraging Uncle Max and his garrulous neighbor, Rose, to spend time together; by the end, Uncle Max follows Rose to her winter quarters in Florida, and offers to trade his roomy apartment for theirs.
