Someone asked me...how it felt and I was reminded of a story that a fellow townsman of ours used to tell--Abraham Lincoln. They asked him how he felt once after an unsuccessful election. He said he felt like a little boy who had stubbed his toe in the dark. He said that he was too old to cry, but it hurt too much to laugh.

 Adlai E. Stevenson
When an American says that he loves his country, he means not only that he loves the New England hills, the prairies glistening in the sun, the wide and rising plains, the great mountains, and the sea. He means that he loves an inner air, an inner light in which freedom lives and in which a man can draw the breath of self-respect.
 Adlai E. Stevenson
