You come to a point in your life when you really don't care what people think about you, you just care what you think about yourself.
But in a larger sense, we cannot dedicate, we cannot consecrate, we cannot hallow this ground. The brave men, living and dead, who struggled here, have consecrated it, far above our poor power to add or to detract. The world will little note, nor long remember what we say here, but it can never forget what they did here.
