Dear (имя того, кому пишете письмо) , (не забываем про запятую!)Thank you for your letter.Autumn holidays were so much fun! Together with his friends, I went to the premiere of a horror movie.It was so fascinating! Now I understand why people like 3D films! It is really fantastic! By the way, my dog gave birth to puppies. They are so cute! Unfortunately, however, my parents were not allowed to leave them at home. At the time of the autumn holidays we asked a lot of homework. It was heavy and lazy, but I did it!What about you?How did you spend your autumn vacation? Write me back!Yours,Selly.(или другое имя)
