Dear Jack,
Thank you for your letter! I'm glad to hear that you started playing the guitar; it’s such a fun instrument! I also enjoy playing the piano, which has been a passion of mine for years. My favorite hobbies are painting and reading. I usually dedicate my weekends to these activities when I have more free time. They help me relax and express my creativity. Let me know how your guitar playing is going!
Looking forward to hearing from you soon!
Best,
[Your Name]
