This makes me grateful for the place my dad lives. Very active community there, and many residents eat dinner together in the communal dining room daily. Food is excellent too. But tbh most of the time I go there there isn't usually a lot of people roaming around. A lot of people are out at dinner time, and you'll see groups in common rooms gathered for some activity, but otherwise people tend to be in their apartments. I think they're just old and walking is difficult.
