Dr. Stanley Goldstein - Author and Psychologist

Central to psychotherapy is the concept that behaviors can have symbolic, often unconscious motives. For example, a potentially dangerous road rage action can indicate both annoyance at another's driving but also anger from another situation: a workplace happening, an interaction in a relationship, or a lingering emotion from childhood.
Thus, missing several psychotherapy sessions without reasonable cause (illness, hazardous driving weather, death in the family), especially if the therapist isn't notified but left waiting, can reflect diminished interest in treatment, be an indirect expression of anger, or indicate excessive narcissism, the feeling that the world revolves about them.
 The therapist then has two choices: to accept that, in their patient's current level of emotional development, they cannot behave differently; or, if excessive, to end treatment. It is not unreasonable to expect simple courtesy from all.
