Amanda, our hospice nurse, answered the door when I rang the doorbell, showed me where to leave my shoes and escorted me into the den, where I found Faiz’s mother, Haima, sitting on the floor. Haima apologized that the air conditioner was out again, for the second time in a week. Within minutes, my slacks and blouse stuck to my skin, and the air in the den felt heavy despite a frantic fan and the open window in the breakfast room.
