18. began 19. Hi Steven, Thank you for your letter. How are you? I'm (13) years old. My birthday is on (23rd September). I have one sister. She's (15) years old. I got many presents for my last birthday. There were a really interesting book with pictures, small Teddy bear and wool sweater. I was very happy that day. Write me soon. Love, (Name)
