For a long time I knew all the neighbors in my 16-apartment building: their names, occupations, hometowns. Then apartments began to turn over faster, and less-friendly young people moved in, generally to renovated spaces where they were paying 3 or 4 times the rent of the long-timers. I suppose they didn't have time to socialize when they had to work 2 jobs to pay for a place with a real bathroom, rather than a tub in the kitchen like I have.
Yesterday, my neighbor told me she had let the police in to do a wellness check on a nanny, except the guy in that place isn't, & is fine, & I realized which apartment they must have meant (if they had the right building at all). And I realized that I once again know most of my neighbors, at least by sight & to nod to. I believe the next few years have to be about community, standing up for & protecting each other. Knowing who's in the Ezra Pound: it's a start.
