Cathy is Rachel’s roommate and longtime friend since their university days. Niceness, Rachel believes, is Cathy’s defining quality—no matter how many times Rachel gets into trouble or makes a drunken mess, she feels that Cathy will always accept her as she is. As Rachel descends deeper and deeper into her struggles with alcoholism, however, Cathy takes a stand. She serves Rachel with a formal eviction notice (though she later rescinds it) and becomes determined to help Rachel stop drinking, find a new job, and get back on her feet. Cathy’s faith in Rachel’s capacity for change and self-improvement never wavers, and her generosity and patience toward Rachel are seemingly boundless.
