What does it mean if a paitent is voluntary?
I ought to know because I've stayed at mental wards myself. But I don't know if US medical terms of the 1960s are different to Australian medical terms of today.
Harding says to McMurphy that he is not committed, but voluntary and that he can go home anytime he want.
So this means that Harding is still a patient at the ward, but he is allowed to go home for visits? Or does he have the choice to make himself discharged from the hospital altogether?
