How do you tell a man to go away in hard language? Scram, beat it, take off, take the air, on your way, dangle, hit the road, and so forth. All good enough. But give me the classic expression actually used by Spike O'Donnell (of the O'Donnell brothers of Chicago, the only small outfit to tell the Capone mob to go to hell and live). What he said was: "Be missing." The restraint of it is deadly.
