Socialization?

I visited my mother today and it was another one of "those" days where we talked about her age and her death and I couldn't get her interested in any other topic.  When I left the apartment and went out into the lobby, a gentleman was there setting up for a puppet show and the chairs were nearly filled with other residents.   I stood there and thought for a long time about going back and inviting her to come up and watch the show with me, but then realized that she would probably just say that she didn't want to and, sadly, I left Atria and came on home.
