Antonio Rivera took refuge with other Nationalists in the Alcázar during the Spanish Civil War. As a pacifist, the youth refused at first to help defend the ancient stronghold, and was put on latrine duty. When the situation of the besieged became more desperate, he decided that it would not be inconsistent with his principles to aid in the defense, provided that he did not kill in hatred. He was assigned the position of loader to a heavy machine gun. It was said that he would give the signal to fire with the words: "Tirad—pero sin odio." (Fire—but without hatred. )
—Bartlett's Book of Anecdotes

When you're young, you always think you'll meet all sorts of wonderful people, that drifting apart and losing friends is natural. You don't worry, at first, about the friends you leave behind. But as you get older, it gets harder to build friendships. Too many defenses, too little opportunity. You get busy. And by the time you realize that you've lost the dearest best friend you've ever had, years have gone by and you're mature enough to be embarrassed by your attitude and, frankly, by your arrogance.
—Kate Jacobs in The Friday Night Knitting Club
The best defense against the atom bomb is not to be there when it goes off.

Don't ever take a fence down until you know the reason it was put up.
