"You know that game we sometimes play, sitting in a square in the Nest, tossing a ball around? Courage is like a ball, son. A person can hold it only so long, and then he's got to toss it to someone else. When it's tossed your way, you've got to catch it and hold it tight--and hope there'll be someone else to toss it to when you get tired of being brave." -- from "A Pail of Air" (1951), by Fritz Leiber (b. 1910-12-24, d. 1992-09-05)
