Athol Fugard: It can be very exhausting, and there comes a moment in the writing of any play where you just wish, “Oh for God’s sake, do I have to go on? Can’t I just push this aside?” But you get back to it. And there’s one sort of touchstone. If you know what you’ve put on that page is truthfully how you feel, what you understand about a character you’re writing about, if it rings true, that’s the only yardstick you’ve got. I phrased it once or twice in interviews as saying — attempting — to be a truly honest witness that will tell the truth, the whole truth, and nothing but the truth, so help me God.
