Dear Oliver,
Thanks a lot for your letter. It was great to hear from you!
As for my weekends, I usually spend them playing football with my friends in the park. Sometimes we go to the cinema to watch a new film. This weekend I'm planning to visit my grandparents in the countryside. I see them quite often, about once a month. They always have a lot of interesting stories to tell.
What about you? What are your plans for the next weekend?
Best wishes,
