Mr. Wilder, Mr. Baxter, and Ms. Kubelik.
The people who inhabit The Apartment are people we have all encountered. We have seen both the takers and the people who get took; we've probably even experienced it for ourselves. The plight of Fran Kubelik would be pathetic if it weren't so heartbreakingly honest. She has fooled herself into believing that Mr. Sheldrake has the ability to love her unconditionally when the truth is that he only appreciates the pieces of her that he can exploit. Her capacity for love is preyed upon because Sheldrake knows it means she will always be there when he is ready for their next rendezvous. He doesn't want any part of the things that make her complex because that would make her human. When she cries, he chides her for not being the "fun" Fran he used to know. Her unsuccessful suicide is tragic only because it interrupts Christmastime with his family.
