Motifs and My Interpretation

In the story metamorphosis one motif is the family as a unit. Towards the end of the book (more so in the last paragraph) they are talking about this newer smaller apartment on the outskirts of town. Well in our class we had a discussion whether it was right of Gregor's parents just to leave or not. Well in my point of view this is best for them. I think that the old apartment symbolizes Gregor himself. The transition in the end of the 2 apartments is like the family moving passed what happened with his transformation and death. It even says at the end the the daughter stretch her young body and I think that that symbolizes the family just having a load taken off of them.
