Question

Dear Sam,
 Sorry I haven’t written for so long but I have been a trip in the mountains for two weeks. I want to share with you my impressions. It was the most exciting trip in my life. I had a dream that I will go to trip and my dream came true. I was so happy! 
 In the trip our group and I climbed on a big mountain in the west of South America. It was so long and we always was get tired to the end of a day. But it was even interesting. We cooked a meal on fire and it was very tasty! I liked the trip.
 Anyway, I have to go now because my Mum asked me to help her with the washing up. Take care and keep in touch!
With best wishes,
Tanya

Dear Sam,
Sorry I haven’t been writing for so long but I was on a trip to the mountains for two weeks. I would like to share my impressions with you. It was the most exciting journey in my life. I had a dream about traveling and my dream came true. I was so happy! Our group and I climbed a big mountain in the west of South America. It was a very long and exacting climb, and we always got tired by the end of a day. But it was very exiting and interesting at the same time. We cooked our meals on fire, and they was very tasty! I enjoyed that journey tremendously.Anyway, I have to go now because my Mum has asked me to help her with the laundry (или the dishes? или cleaning the house? Что вы хотели сказать? ) . Take care and keep in touch!
With my very best wishes,
Tanya
