"I left school in the 6th grade. When I was young I fought with my father a lot and he didn't take care of us. We were 16 siblings in all and we sort of raised ourselves. Ten of us are still alive. I have three sons and two daughters but they don't take care of me. I am just trying to survive." - Maria Lopez Pega is a street vendor in Havana, Cuba and sells candy and chicharrones.
