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 usually spend my free time reading books. As for me, I try to read every day, if possible, for about an hour. So, I usually read alone because I like to concentrate on the story.
Sorry, I have to go now. My dad asked me to help him in the garden.
Write back soon.
Best wishes,
[Ваше имя]
