Answer:
On a dark winter night outside Elsinore Castle in Denmark, an officer named Bernardo comes to relieve the watchman Francisco. In the heavy darkness, the men cannot see each other. Bernardo hears a footstep near him and cries, “Who’s there?” After both men ensure that the other is also a watchman, they relax. Cold, tired, and apprehensive from his many hours of guarding the castle, Francisco thanks Bernardo and prepares to go home and go to bed.
