It's a great way to brush up on any subject and to appear worldly. I suspect that anyone who doesn't have time to sit and read a book could still find time to read one standing up, or is probably so busy making wheelbarrows full of money that he could afford to hire a lackey to follow him around, reading a book aloud. Worldly is easy to do, anyway. I used to do worldly pretty well, back when I smoked. Worldly people always smoke.
French cigarettes are best, or Picayunes.
Probably not since they invented marijuana. Any rate, all you do is put on a trench coat and sit around with a sullen look and a lit cigarette hanging out of the corner of your mouth. It takes some practice not to let the smoke make your eye water, unless you're doing brokenhearted worldly. And keep your mouth shut.
