I volunteered briefly at an inpatient hospice unit. My job was basically to visit with whomever in the room would talk. Most of the time, the patient was comatose, and the family members were sitting around waiting for their loved one to die. The boredom, tedium, and stress experienced during that time is palpable, and family members are somewhat desperate to talk to someone - anyone about their loved one, family, what they are going through, etc.
I also had conversations with some of the patients themselves. Mrs. Breer, who was 100, was originally from Germany and during WWI (in the US) was sent to a boarding school to protect her from the anti-German sentiment in this country. She vividly recalled Armistice Day, and how the nuns let them have the day off. She was also an early resident of my neighborhood, and told me how far out in the country it was in those days, and how things grew up around her. I still think of her when I drive by her house.
Needless to say, my volunteering, just to listen, was extremely meaningful to me, and to the families. I have worked as a CPA for many years and done a lot of other things, but the only time I've been thanked or mentioned in an obituary was after I spent an hour or two with a man whose mother died later that evening.
