I worked with the elderly in a nursing home during my time of the service (in Germany, instead of the military service, there was an optional public service in social institutions). It was nice, in a way, the residents tended to be very grateful, and enjoyed socializing. However, they were people as we all are, and sometimes didn't get along, or just felt like annoying others. Not so nice, but then again, we all feel like that sometimes, including myself. So why not? Let them be humans.
