I love the sound of street vendors in Bangalore, because they remind me of the street vendors in my old neighborhood when I was growing up in Vietnam. These people are poorer than poor. They usually walk and carry heavy things for many kilometers, just to make a few rupees. Their voices are beautiful, insistent, and sometime daunting. As conditions in Asia become more advanced, soon these people will no longer be needed. And their beautiful sound will be replaced by the modern silence, like what we have in the States.
