Dear Julia!
Thanks for your previous letter. I'm sorry, but I couldn't write you quicker, as I was busy with my studies.
You've said, that you are going to take a trip to Paris, but you French is not very good. I must tell you, that in France you can speak English, and French people will understand you. I was in Paris last year, and everybody understood my English.
Personally I started learning English since I went to school, at the age of 7. Now I have 4 English lessons a week. But I have always wanted to learn Italian, because it is very beautiful language in my opinion.
Now I must go, because I have to help my mother in the garden. Write me soon.
Love,
Ann.
