Yet it was never an equal friendship. From the beginning Patchett was the giver and Grealy the taker.
Grealy, who died from a drug overdose at the age of 39, underwent nearly 40 operations in her short life because of a facial disfigurement caused by cancer of the jaw. Even though her vibrant personality resulted in more friends and lovers than most other women could imagine, she became dependent upon Patchett to reassure her constantly that, yes, she was loved and, however her ever-changing face happened to look at the moment, she would have sex again.
Never able to manage money, nor anything else, Grealy gave no thought to paying her mounting medical bills, and she would just move to another apartment whenever her landlord became too demanding. Patchett, or some other friend, was always there to help her out and take care of her after those frequent surgeries. At one point Patchett even offered to write her novel for her.
Eventually Grealy became addicted to painkillers, then resorted to harder drugs, all the while insisting she was not an addict. She died in 2002, and Patchett's book came out in 2004.
