Dear (имя человека, которому пишут письмо),
How are you? I am fine. I'm looking forward to amazing summer holidays.
This year I decided to go to Rome. And I also bought tickets. I'm going to do a lot of sightseeings. For example, Coliseum, The Plaza Of Spain, and so on. I also really want to go shopping, because I want to buy a new phone. I am going to take a lot of photos to show you when I come back.
See you next month,
Love
