Sure, here's a sample letter to a friend about weekend plans:
Hi [Friend's Name],
I hope you're doing well! I wanted to share my plans for the weekend with you. On Saturday, I'm thinking of starting the day with a long walk in the park to enjoy the fresh air. In the afternoon, I'm planning to visit the new art exhibition downtown. I've heard great things about it! On Sunday, I'm going to relax at home, maybe catch up on some reading, and in the evening, I'll have dinner with my family. What about you? Any exciting plans?
Take care,
[Your Name]
