Dear Mary,

I'm fine. And you? I'm very glad writing letter to you. I will tell you about one of my most memorable past experiences. Last month, my mother told me to bring a raincoat before I went to school but I did not obey. When I went home, suddenly it rained. It rained more and more heavily. I decided to go home in rain without raincoat. That night, I'm seriously ill. I was pity when seeing my parents looked after me and worry about me.

I hope you won't do it as me. I look forward to hearing from you soon.

Your friend,

Mai
