Passive-aggressive behavior is characterized by a pattern of passive hostility and an avoidance of direct communication. Inaction where some action is socially customary is a typical passive-aggressive strategy (showing up late for functions, staying silent when a response is expected). It is typically used to avoid confrontation, rejection, or criticism. Passive-aggressive behavior is sometimes protested by associates, evoking exasperation or confusion.
