It’s pretty easy to volunteer when you feel like the task you are doing is big and important. But when the job seems mundane and messy—maybe even smelly—some volunteers might hesitate. In Serve the City, however, volunteering with humility means we are not too proud to do the little things, and to clean up things that are are dirty. And this includes not just dirty streets, but dirty bits of history that pollute our cities. 
This episode contains three stories from three continents in which people doing small, humble things together are making a big difference.  Our first story, from Lusaka, Zambia, features a massive crowd—including some people who might be considered too important for such tasks—who work together to clean their streets. In Berlin, Germany, the site of our second story, volunteers go down on their knees to clean, not just the streets, but a city's memories of persecution. And in Hampton, Virginia, in the USA, volunteers put their backs into paying respect to some long-dead residents who were not respected in their lifetimes.
