You are about to start the greatest improvisation of all. With no script. No idea what's going to happen, often with people and places you have never seen before. And you are not in control. So say 'yes. ' And if you're lucky, you'll find people who will say 'yes' back.
And in a democracy, when we say we're mad at what's going on, what we need to be saying is we're mad at ourselves.
