"In... you see,in their last moments,people show you who they really are."

This dialogue introduces you to the real world in which we actually live.This dialogue was spoken by the Joker in the 2008 movie "The Dark Knight".Most of the people in today's world fake about what they are  and create their false impression in the society.Even most of the people you know act in a faking manner in front of you.But if you stop fulfilling the purposes for which they are faking,they start showing you who they really are.These are hence there last moments because after these moments they do not need you any more.They know that once you have stopped fulfilling their purposes,you are of no further use to them and hence,they show you who they really are.
