A city is where you can sign a petition, boo the chief justice, fish off a pier, gaze at a hippopotamus, buy a flower at the corner, or get a good hamburger or a bad girl at 4 A.M. A city is where sirens make white streaks of sound in the sky and foghorns speak in dark grays. San Francisco is such a city.
Sometimes I want to just pull the off switch, but you can't because if you go outside, you have to give people your all. You can't say, 'Oh, you know what? I'm not feeling good today.' No. No one's trying to hear that. When a woman comes up to you and says, 'Hey, my daughter's your biggest fan. Can we have a picture?' - you can't say no.
