Three of the cardplayers were called by last name only, Dockery, Rumsey, Hovanis, and two by first name, Demetrius and Keith. Terry Cheng was Terry Cheng.
Someone told Rumsey one night, it was Dockery the waggish adman, that everything in his life would be different, Rumsey's, if one letter in his name was different. An a for the u. Making him, effectively, Ramsey. It was the u, the rum, that had shaped his life and mind. The way he walks and talks, his slouchings, his very size and shape, the slowness and thickness that pour off him, the way he puts his hand down his shirt to scratch an itch. This would all be different if he'd been born a Ramsey.
They sat waiting for R's reply, watching him linger in the aura of his defined state.
