I hope that I will have time to go skiing. Maybe it is even better to go at the end of the season. The doctor, however, did not give his diagnosis yet. If I cannot go I will have to find an alternative.
Thanks again for your letter. For now, the weather here is like it is in your country, ice cold. I will write you a letter in Spanish and in English. So you can compare the sentences.
