Dear [Name],
Thank you for your letter. Has it really been two months since i wrote? I'm sorry, but I was very busy lately.
Do you remember that soon will be summer holidays? I would like to spend it with my friends and, of course, with you. I want to go to the cinema and see some interesting films. I like playing some games. For example. football, volleyball and tennis. Do you like it? Also we can spend time on beach, we can swim, play interesting games and talk about our lifes.
Hope you like these ideas. How are you? Please write to me soon.
