Объяснение:
Dear ….(имя друга),
Greetings from Sochi! I am having a wonderful time and the weather is great. It is hot and sunny. We also stayed in a very nice hotel. Our room is very spacious and beautiful, and the view from the balcony overlooks the beautiful sea. Yesterday we went to an aqua park. I was so amazing. Today we plan to go to Sochi aquarium and the Sochi National Park. After that,we are going to souvenir shopping. And we just woke up recently, I'm waiting for my mom and dad to get ready, and we'll go to breakfast.
Sorry, I have to go.
See you soon when i get back.
НАДЕЮСЬ
