David Brooks has a column in the Times today discussing friendships, how many we can maintain at various levels of intimacy. He ends by thinking our friendships have become fragile during the pandemic.
I'm certainly not an expert on friendships--I don't maintain the ones I once have, and since retirement I've not been creating new ones.
I'm not sure Brooks is correct--I know my cousin's extended family has found new community bonds by having weekly zoom calls during the pandemic. Before the pandemic, they were scattered across CA, CO, OH, PA, NH, MA, TX with much less regular contact.
I suspect the issue is what the psychologists call "availability"--we readily notice the changes, the losses, which occur but we are less conscious of the new patterns we're establishing.
