Final answer:
The mention of postmen and doctors likely signifies everyday normality returning after an eventful or dramatic episode in literature, a theme familiar in commedia dell'arte-style performances.
Step-by-step explanation:
The provided text seems to be related to characters perhaps from a play, displaying characteristics of commedia dell'arte. In traditional performances involving characters like the Doctor, Colombina, The Captain, and Pulcinella, the reference to postmen and doctors in the last line could imply the daily routine and normality resuming after the events they have experienced. Since the text does not provide the last line itself, we can assume that the mention of postmen and doctors signifies a return to ordinary life after an extraordinary or dramatic event, which is a common theme in literature.
