Being an opportunist..

Here i am not talking about the opportunity we all are told to identify and utilize.I am talking about those opportunities in which we use someone else to our own advantage, especially someone we know , a close friend or someone like that.Now don't think u never do it.Asking a favor,stealing girl friend,ditching the person who helped us at the first chance we get,making friends for sake of some benefit etc etc.Upto a certain extent we all have done this.
As far as i know we even did not spare our own parents.In fact they are the once we learn speaking lies.Taking money for wrong reasons might be the latest thing u did.
   All i want to say that at some point or the other knowingly or unknowingly we tend to see our own profits and fail to see what price the other person pays for it.Whether in terms of trust or money or time or effort.Whenever we think of our own good instead of common one we really hurt a person and give him distrust,Plenty of reasons to learn a lesson and beware of OUR kind of people or worse how to use a person. 
                        Please don't do that. 
I understand it's very human to fall for temptations,playing mind games,being ignorant,using someone else innocence or fool him and easier is to conjure up explainations  but isn't it your responsibility to become a true human with a very high conscience , become really respectable,and best reason is to respect your self.
Come on think for a moment you look at your own gains,Step into other person shoes, show compassion and don't do that.It may be tough, may mean taking more pains but if you do it over someone else expense trust me it doesn't worth it..
