they go through two big sets of double doors , past the corridor to ward b , past two vast rooms lined with curtained cubicles , turn left again at the closed entrance to gerontology , down a long , long hallway lined with bulletin boards , past the opening to ward c , then take an abrupt right at the men 's and women 's bathrooms , pass ambulatory ophthalmology and records annex , and at last come to a corridor marked ward d. as they proceed , the light seems progressively to darken , the walls to contract , the windows to shrink .
