You can become an alcoholic working in an office in Los Angeles. It's very easy to say because I do this shameful job I take drugs or drink, but the real reason prostitutes take drugs and drink is because prostitution is a party area. It's not about desperation, it's the surroundings.

There's always this problem in society where people know they need these places for social peace, but the fundamentalists want to shut them down. Sometimes that's for economic reasons, because they want to build a supermarket there. The imam will hold a prayer and say let's get rid of the girls, but on the other hand they're all going there.

A young man in Bangladesh can't even hold hands with a young woman. Without marriage there is no kissing, no holding hands, no going anywhere. So young boys can only go to the brothels for sex before marriage.

In Bangladesh a prostitute normally wouldn't even undress for a man. He pays, she pulls up her sari, and he's done in 20 seconds.

If you're a prostitute, this is your day: You party, you have customers until four or six in the morning, then you sleep. You wake at noon, watch soaps on TV, take two or three hours to fancy up yourself, and then you start waiting for customers. That's your life. And some days no customers come. There's no party. There's nothing. You sit there and wait. If you're educated you can read books, but in Bangladesh and most other places you watch TV or listen to music or cook.

La Zona is such a closed area, a dangerous, outlaw area. My time in the Zona was a time outside of society, almost out of the real world. And the girls there had such a sense of irony and sarcasm. They were also really interested in my film. They'd be like, "Thank God we live in Mexico, because our kind of prostitution has a heart. We wouldn't want to sit behind a glass cage or be sold by our own mothers. We have free will."
