Translation of Mäuschen

I have studied French for many hours per week, and I've even lived in Geneva for a while... my French was good than. Today, I have forgotten most of it. I have to re-learn and Vocabulix can help.
Thanks a lot. My wife, daughter and I came back with a flu from the Swiss mountains, but now we are getting better. How are you? 'Vos' is only used in antique Spanish as 'usted', in the singular form of course.
I once had a lesson with a private teacher, but unfortunately she could not come regularly. She was always sick, then I have visited a school in Andalusia, which was worthless, since we talked only German.
