Boston is a city of neighborhoods. Beware the outsider who confuses the South End with South Boston, the North End with Charlestown, or fails to differentiate between Roxbury and Dorchester. And it's the neighbors in those neighborhoods who take it on themselves to make sure their streets are clean, sidewalks repaired, graffiti removed, and lights fixed, among the myriad other things that make a neighborhood desirable.
