Try To Prove Your Point But For That Never Prove Others Wrong

Mostly This Happens That, 
     You Think As If You Are Right At Some Place,
          And Other Person Is Not Agree With That,
               Then That Person Is Wrong At That Point.
                    At Same Time That Person Also Thinks Like He/She Is Right;
                         But You Are Not Agreed With That So You Are Wrong.

But Real Scenario Is Both You And Your Opponent Is Right At Your Respective Point And Situation.

Because You Both Are Not Exactly Aware About Past, Views Or Connected Story Behind That Situation Of Each Other.

It May Be Possible That,
      That Person May Be Wrong But Never Say To Anyone That You Are Fully Wrong At This/That Point;
           Because Based On That Person's Past Situation Or Views, That Person May Be Right At Own Point.

So If You Think That You Are Right At Any Point,
         And You Feel Like Other Person Is Wrong At Same Point,
                  Then Firstly Try To Know And Understand That Person's Situation And Views.
