“It's interesting that my neighbor Irv, who saw dogs so differently, knew all the kids and people on the block and could recite the family history of each house until about a decade ago. Now few of our neighbors can name more than a handful of people who live on the street. They have little to do with local government, and vote sporadically, at best. In the evenings and on weekends, they go their own ways. Their kids are repeatedly warned about talking to people they don't know.”
