Dear Emma,
Thanks for your letter! I was really interested to hear about your brother. It's funny because my family can be annoying too, but most of the time, they're great. I have one older sister. Her name is Sarah, and she's 18 years old. She's really into art and spends most of her time drawing or painting. My mom is a teacher, and my dad works as an engineer. We also have a dog named Max. He's a golden retriever, and he loves going for walks in the park. We all get along pretty well, although sometimes Sarah and I argue about who gets to use the computer!
I see you're meeting your best friend Katie. That sounds like fun! I’m curious about her. How long have you known Katie? What do you usually do together when you hang out? What is the most interesting thing about Katie?
Anyway, I have to go now. Write back soon!
Best wishes,
[Your Name]
