Am i suitable for it?

Gosh. I kept on forgetting that there is someone out there wants  me to teach them how to speak in English. Seriously I was surprised towards his proposal that he sent to me through facebook. Okay I don't really know whether I am the suitable person to do that. BUT BUT i hate to disappoint him because he only admits to me that he can't speak in English. I know it's a normal thing but at least his a guy and a husband and a father who is willing to learn. I salute him for that. Now i have to think on what sort of resources should i give him. *lets think together and you guys help me also . CAN?*
