Pas de deux

I live in France and I started taking ballet classes for beginners. I'm Portuguese, but surprisingly one of the teachers speaks my language. He started giving me instructions in Portuguese when he passes near me during exercises. Also, he has a calm voice and seems coming out of an Italian Renaissance painting. Every move seems super easy when he demonstrates it to the class.

I sometimes wonder how could it be, taking a private lesson and performing with him some kind of "pas de deux".
