In some areas, the avoidance style is used by both members of the avoidance relationship; in others the senior member may talk to the junior in everyday style. Behavior associated with avoidance speech is a continuum and varies between tribes. For the Dyirbal people, a man and his mother-in-law may not make eye contact, face one another or directly talk to each other. Rather, they must address a third person or even a nearby object. For slightly less restricted relationships, such as between a man and his father-in-law, avoidance style is used and must be spoken in a slow, soft voice. An extreme case of avoidance behavior is found in the Umpila, in which a man and his mother-in-law may not speak at all in each other’s presence.
