Hi (имя друга)
Thank you for reply to my email.That was interesting!As for me i prefer trip to the sea abroad(за границу).
I willn't only sunbathe and swim.I'm going to walk around the city,to taste unusual food,try different activities (пробовать разные развлечения),go shopping and much more. I really want to see the dolphins and take some photos of them.At the expense of animals(на счёт животных/что касается животных),i would lik to go to the zoo if it was there.
I will be going to the sea not only with my family,but with my cousins too.We haven't yet decided which country we will go to breathe.
Sorry,i must to go.Good luck and bye!
