Dear, friend I am going to spend this weekend at my grandma's cottage in the countryside and I want you to go with me. I will help my grandma with garden and cooking. If you want to come with me, it will be great! Well, if you want to go with me, write me back. See you soon [Ваше имя] (БЕЗ точки в конце, ибо если с точкой, то это ошибка, и на экзамене вам просто напросто проверяющие не засчитают).
