There was a time when people treated their neighbors like family, and this is still true in many parts of the world. But across much of the U.S., we tend to treat our neighbors as an annoyance, contacting them only when we need something or want to register a noise complaint (did we learn nothing from Mr. Rogers??). This emphasis on individualism over community can have tragic effects on our health and happiness. But when we do make the effort to reach out to our neighbors from a place of love, kindness, and generosity, we never know when we might uplift someone or even save their life. And besides, it would make Mr. Rogers proud.
