Imagine this: It is a cold winter night. You are five years old, hungry and huddled under an apartment stairway. You are unprotected from the wind and snow, and unprotected from the drunkards around you. You sit in a corner, shivering and crying for fear that you might be attacked.Most adults would be intimidated, let alone a child.Yet, Burenkhaan Erdenechimeg had to live through that as a young five-year-old Mongolian boy. Not only would he and his mother collect glasses and cans to survive, he eventually lost his mother on the streets.
