Brushing up my Italian

This evening, I am supposed to have dinner with my friend, Italian and former colleague, and her boyfriend, who is visiting her from Italy. Little detail of some importance: the man speaks very little English. So I need to brush up my Italian. I am glad. I will have a good occasion to practice and to improve. Of course, I haven't studied it in a long while, but nothing like immersion to get better. Well, immersion, it will be one to one immersion, not exactly like being in Italy with monolingual people, but still.
