Right Ho, Jeeves 

‘Jeeves, ‘ I said, ‘may I speak frankly?’ ‘Certainly, sir.’ ‘What I have to say may wound you.’ ‘Not at all, sir.’ ‘Well, then——’ No—wait. Hold the line a minute. I’ve gone off the rails. I don’t know if you have had the same experience, but the snag I always come up against when I’m telling a story is this dashed difficult problem of where to begin it. It’s a thing you don’t want to go wrong over, because one false step and you’re sunk. I mean, if you fool about too long at the start, trying to establish atmosphere, as they call it, and all that sort of rot, you fail to grip and the customers walk out on you. Get off the mark, on the other hand, like a scalded cat, and your public is at a loss. It simply raises its eyebrows, and can’t make out what you’re talking about.
