Thank you for your last letter. Here are photos of me and my

We both like sports, although Liu Ying is more athletic than me. She’s more outgoing, and I’m quieter. I think I’m smarter than her. My favorite subjects are physics and chemistry, and her favorite subject is P.E. However, we both enjoy going to parties.
