Dear Anna,
Long time no see? How are you? I'm ok. Next week, I got 2 tickets to go to the cinema. I was so happy. The first time, I invited my cousin but he had a class at that time. So I write this letter to invite you to go to the cinema with me next Monday. You can come to my home first then we will have dinner before the film started.
Hope to hear from you soon.
Love,
