Helping someone is all about inner conviction rather than expecting favor in return. It is all about doing the necessary to save a critical situation. The occurrence of this opportunity is called Altruism, it may also be defined as an activity repaid with an intrinsic reward and extrinsic gain. This is related to role taking in the sense that it involves a form of responsibility. In some cases, this exchange may be unfulfilled yet it does not make it any less of an altruistic relationship but does press for the reasons of human behavior.
