How did the charwoman disposed Gregor's body?
Franz Kafka’s The Metamorphosis is a story that work mainly on a symbolic rather than realistic level. The basic premise, that a person can wake up having been turned into a cockroach, suggests to us as readers that we should search for metaphoric interpretations of events rather than naturalistic details.
The cleaning woman announces to the family that Gregor’s corpse has been taken care of, but she does not give us details of what precisely she does to take care of or dispose of it. On a symbolic level, this reminds us that the work of the lower classes, of servants, was invisible to their masters, and that they would “take care” many of the unpleasant details of daily life almost invisibly.
