Maybe if you say NO, your friend will learn the most important lesson you have ever taught him: that he is free to do whatever he wants with his life but not involving others. Stop feeling responsible for him. It is not fair to start a project relying on others, at best it is immature and irresponsible, at worst I would say: what a cheek!

I design my courses (for French, not for English) and I love doing it. I have courses for all levels, for adults, teens and children.

One of my courses is for teens. I wrote a detective story in chapters. After each reading , there are grammar and vocabulary exercises, listening and speaking actitivities. The listening activities are from the internet. As I give only private classes, there is no problem. The exercises I make myself, of course I take my inspiration from books. The good thing is, it �s never finished, and I improve it after each student. The kids love it because they want to know the story (who the criminal is). I have tried with Gloria to make an English version of the method in order to publish it for public schools in Brazil, but as there isn �t such a possibility, we gave up.

If you are creative, try to make your own course, it �s really funny.
