Deat friend,
I'm happy we will be penfriends. Let me tell you a few things about myself.
My name is David Parker. I'm 12 I live in Melbourne It's a nice big city. I have a brother and a sister. Have you got any brothers or sisters?
In my time. I enjoy swimming and playing basketball with my friends. I play for the school team. Can you play basketball? I also like browsing the internet and playing strategy games. Do you like playing computer games? What is your favourite game? At school,I really enjoy English and Spanish. I like languages. I'm going to learn Chinese soon because I have a penfriend from China and I want to visit this country one day. Have you got any favourite subjects?
Well,that's all about me. I'm looking forward to hearing from you.
Best wishes,
David
