There is one quote by Bob Marley which is one of favs. It sounds really arrogant but then how true is it for those who love to critisize others without reason... Have a look: "Who are u to judge the life I live? I know I am not perfect- N I don't live to be. But before you start pointing fingers... make sure your hands are clean" Keep Smiling! And next time someone criticizes you irrationally, you know the answer:D
