Bardzo serdecznie proszę o sprawdzenie kilku zdań i ewentualne poprawki. Z góry dziękuję.
You can send me postcards with photos of the most beautiful places in your country or something typical for your country.
Postcards with something or somebody you like. ( your hobby, favourite actor etc.) are also welcomed.
Please, write a few sentences about yourself. If you don't like doing that you can write something interesting about your city or country.
Would you please write greetings or any phrase in your language (with translation of course :)) ?
I'm looking forward for your letter.
Best regards from Poland:)
