Playwright Dan O’Brien: “When you or a loved one are gravely ill you can’t help but feel that now is undeniably, inescapably now. … When one is gravely ill, anything can happen, and sometimes does. In a play, anything can and always does happen. Must do. Every moment a potential calamity. We’ve all seen an actor go up on her lines. Disaster. Beautiful. You can hear a pin drop.”
