Jennifer's Ground Privilege Card, which allowed her ground privileges and responsibilities, as stated on the card:
Ground Privileges are given to patients for treatment purposes. The patients receiving them should be able to conduct themselves in keeping with the responsibility expected of them. They will be revoked for those patients who demonstrate that they cannot assume the responsibility. Any patient on the grounds unaccompanied by personnel may be asked to show his ground privilege card and should carry it on him at all times.
Jennifer found this card in 2012, among her papers.
