Как написать письмо другу и ответить на его вопросы?

Dear David,

Thank you for your letter! I'm glad you had a great time in Greece. I usually spend my holidays with my family at the countryside or visiting other cities in our country. Last time, we went to the seaside and enjoyed swimming and exploring the local culture. It was a wonderful experience.

Looking forward to hearing from you soon.

Best regards,
[Your Name]
