The Professor lives in Brooklyn; her partner Nathan left her when she couldn’t have a baby. All she has now is her dead-end teaching job, her ramshackle apartment, and Nathan’s old moggy, Cat. Who she doesn’t even like.

The Actress lives a few doors down. She’s famous and beautiful, with auburn hair, perfect skin, a lovely smile. She’s got children - a baby, even. And a husband who seems to adore her. She leaves her windows open, even at night.
