Talk about a respect for the small details of NPC in GTA5, when you pull the girl in the street to the alley XXX finished, if you follow the girl, you will hear her in the phone, and the phone content is to tell the family members in their own "great" life state, so as not to let the family worry about themselves.
To capture the little details, I think, even if is an NPC, also have their own life, maybe we are playing a game, but it is not just this game with us a part of the world, is not of this world each element is for the sake of the existence of "I", in that case, respect for NPC is respect for the game, respect for their own a performance?
