Dear Nick,
I was very glad to get your letter. Sorry, I should have written earlier, but I was busy at school. In your message you asked me about foreign languages.
I learn English since the early childhood and now it comes easy to me. I don't know the best way to learn a language, everyone learn differently. As for me, I read a book and watch films in English, because I want live in London. Yes, I want learn Portugalian language.
And now about your sister. Where did yous sister's graduation take place? How long did it last? Was it exciting?
Sorry, I have to go. Write back soon.
Best wishes,
Anna
