Dear Friend,
Thank you so much for your lovely letter. I really enjoyed hearing from you. In my holidays, I usually visit the seaside or go to the mountains. I love relaxing on the beach and swimming in the sea. Sometimes, I prefer hiking and exploring nature. My most memorable trip was a vacation to Italy, where I saw beautiful cities, tried delicious food, and learned about history and culture. It was an unforgettable experience. I appreciate your asking and hope to hear more about your adventures soon. Thanks again for your letter!
Best wishes,
[Your Name]
