"The saddest moment of my life was when my son left for America. I begged him not to go, but it was no use. He was my son but also my best friend. He used to tell me everything, but all he tells me now is: 'Don't worry, I have a job. I'll tell you everything when I get back.' I think he just doesn't want me to worry about him. Because I heard from his friend that he's being badly mistreated."
