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,
Dear Jenny,
Last night I had a scary dream. I was walking along an empty street late at night. Suddenly a lion appeared at the end of the street. He ran toward me with his big mouth open and sharp teeth. He roared and jumped upon me. I screamed loudly and awoke. I'm still frightened now. By the way, how have similar problems now. Write to me as soon as possible.
Your friend,
Son
