Dear Ben,
Thank you for your nice email. I was happy to hear from you again.
In your email, you asked me about my free time. Well, I love spending my free time reading books. As for me, I usually go for a walk in the park or listen to music. So, I often spend my free time with my family, watching movies or playing board games.
Sorry, I have to go now. My dad asked me to help him in the garden.
Write back soon.
Best wishes,
[Your Name]
