He renders essential services to a community. In fact, he is an important link between a locality and the outside world. He comes door-to-door in his daily rounds to duties and delivers the things: letters, telegrams parcels etc. He holds a responsible job. An interview letter or an appointment letter of a person may be cancelled for mis-delivery or late-delivery. He brings happy news to someone and sad news to some other.
