My first course to conduct

Next week, I'll be conducting my first course infront of our new clients. I heard they are from Greece. During one of the Pizza Days (only Fridays), my boss was telling to us that I'd be the one to conduct. here's our conversation:

boss: Don't you know that bing would conduct here first course.
me: you must be kidding (laughing). I can prepare the devices for you.
boss: Boss A sent an email to me, he suggested to have you because you speak well in English.
me: nobody told me (not yet believing and still laughing). you must be kidding!
boss: you can ask the marketing dept. they already knew that you're the one to conduct. We'll do together, don't worry.

'Don't worry' was true at the moment. Obviously I was surprised yet happy. From that noon, my mind was grilling on the 'content' of the course. I am not worried on the medium of speaking which I prefer, I am not fluent (in its meaning) in italian. There are times that my italian conversation is mixed with some tagalog/english/ilocano words! hehehe Anyway, I am able to express myself (thanks God!) and to be able to understand them. Now, I am thinking on the 'content', what to include on my 'blah..blah!'.

I have to work now.
