The American -
The male protagonist of the story. The American never reveals his name, nor does the girl ever directly address him by name. He is determined to convince the girl to have the operation but tries to appear as though he doesn’t care what she does. He remains disconnected from his surroundings, not really understanding or even listening to what the girl has to say.
The Girl -
The female protagonist of the story. The American calls the girl “Jig” at one point in the story but never mentions her real name. Unlike the American, the girl is less sure of what she wants and appears reluctant to have the operation in question. She alternates between wanting to talk about the operation and wanting to avoid the topic altogether.
