I agree with Lizzie about learning the language of the country you live in. I'm trying to teach literacy and French to Moroccan and Turkish ladies and they all want to learn how to call the emergency services, how to make an appointment at the doctor's or the dentist's and I insist on the fact that they must make themselves understandable. What if they're wounded in an accident and unable to give their relatives' names and addresses properly? What if they need to call the fire brigade? We've been practicing and you can't imagine how many times their houses would have burnt down because they couldn't say their address. How do they manage to explain what kind of pain they feel and how long it's been lasting? How do they communicate with their children's teachers? Should they stay like ever-lasting children, unable to manage by themselves?
