Read the excerpt from "The Love Song of J. Alfred Prufrock."And indeed there will be time To wonder, “Do I dare?” and, “Do I dare?” Time to turn back and descend the stair, With a bald spot in the middle of my hair — (They will say: “How his hair is growing thin!”) My morning coat, my collar mounting firmly to the chin, My necktie rich and modest, but asserted by a simple pin — (They will say: “But how his arms and legs are thin!”) Do I dare Disturb the universe? In a minute there is time For decisions and revisions which a minute will reverse. Which words best indicate that Prufrock feels uncertain?
