First, I realized that there aren't 30 students in my French class. I thought I heard the teacher say 29 at one point, but I must have misunderstood. But that's why I'm in French class, right?
It's more like 22-23ish.
Today (day 4), there were 21 of us in class, and we learned how to say our nationalities/countries of origin in complete sentences. Here's what I caught - I missed one or two, but this is pretty close:
A room with 21 people, 15 countries represented. That, my friends, is Luxembourg for you.
P.S. Je viens des Etats-Unis. Je suis américaine.
