Dear [Friend's Name],
Thank you for your last letter! It was great to hear from you. In your letter, you asked me about my summer plans. I am excited to tell you that I will be going to the beach with my family next month. I can’t wait to relax and enjoy the sun!
Let’s keep in touch and share more about our adventures. Write back soon!
Best wishes,
[Your Name]
