I think it depends a little on where you live, the neighborhood and its micro-social order. For example Berkeley High School lets out for lunch hour and the kids clog the downtown like obnoxious pests. There is a kind of adult collective relief when they go back to their giant prison compound next to city hall and get out of the park across the street. A similar scene is duplicated at Willard middle school at or around three. It's near to a small shopping and restaurant area around Ashby and Tele.
I live in a heavy student area but just a block or so south of me is a quiet residential area with lots of street barriers and a lot of families with kids. The playground of the nearest school is usually pretty full after school in good weather. I was surprized in the long ago, just how kid friendly Berkeley was in programs, schools, field trips, interesting places to visit. The lower grades in this particular area with two elementary schools nearby often take their classes on walks around the downtown area which also includes the main branch of the library. The city hall, main library, and most of the high school were built under WPA projects and all centrally located. In this plan, you can see how a city literally constructs its society as a living entity.
Another civilizing influence are the social science departments including education that kind of permeate the city's institutions in social services. This helps mitigate the endless neoliberal regimes.
