I call you children because that is what you are. You have not fended for yourselves, you have not felt the terrible blows that life gives you. As we speak, there is hatred and prejudice residing in our world's heart. Now a man can make a difference in the world, even if it is a small one. We all have fates, including me. We can choose to make that fate one that will bring hope, or one that will bring destruction. Times are changing, and we must grow wiser for it. So now I must encourage you- I must beg you-when you leave these school walls and enter this world, to not be as idiotic and imbecilic as the generation before you.
