Trun Van Pha, 5, hugs his mother, Ly Thi Mui, 42, as they sit in the grass next to the Red River enjoying the sun. Mui, a Buddhist, has been living homeless for the last five years on the streets of Hanoi, Vietnam, with her son, Pha. Even though they face many daily challenges, and have very little means of survival, they have an overwhelming sense of hope because they find happiness in their simple affection for each other.
