Peruvians call the kids on the street that gather around tourists piranas, after the flesh eating fish. The people selling to cars at traffic lights are called venadors ambulantes, and there are always throngs of them. The traffic cops are always young woman, who suffer general disregard by drivers in addition to the incredible fumes. The buses are always very full and the taxis are so many they're always empty; on the sidewalks people are walking, buying and selling, eating, talking on the public phone, meeting friends and chatting. Everyone is always on the street.
I saw that "O Brother Where Art Thou?" is translated as "O Hermano Donde Esta?" I like that.
