May it be known that there shall be no such event, allowed or even acknowledged. May it be known that if there is such move by others, they must withdraw from it for I shall never acknowledge or endorse such... Be it family or Ef (extended family) or any other... it is not going to be with any consent. "It shall only drive me to some isolated unknown location which shall never be known by any. Period!" The actor -- who came to be known as Bollywood's Angry Young Man and Shahenshah -- has had a successful career, which is going strong even at this age.
