Therapy For Passive Aggressive Behaviour If a child is not allowed to go out to play, he will not eat as a sign of protest even though the hunger is painful. Taking addictive substances are expressions of PAB or Passive Aggressive Behaviour where the sufferer knows how harmful it is but continues his drinking or drug use to protest against one or more authority figures in his/ her life. Every sufferer has a story of his best intentions being thwarted by a parent, teacher, uncle, cousin or boss. Deep down his subconscious minds keeps creating authority figures for him/her to protest against. Therapy identifies authority figures, heals the inner children that had the experience of suffering them, even allows forgiveness and thereby cuts the behavioural loop of defiance of authority.
