Dear Alice,
I haven't talked to you for a long time. How are you doing now? I'm free now so I'm writing this letter to tell you about my free time.
I usually surfing the Internet on my free time. I have plenty of favorite websites and I also write lots of emails. Generally speaking, I see the internet as a good thing. In addition, I enjoy watching movies. I watching comedy and cartoon because it's make me feel funny and relaxed. Finally, what I to do in my free time is listening to music. I prefer pop music most. However, I also enjoy listening to rock music and sometimes classic music, it depends on my mood.
What about you? What do you do in your free time? Write me soon.
Best wishes,

Duong
