Dear brother,
I just wanted to let you know that my new school is going great, I’ve made so many new friends and I’m not getting as much homework as my old school gave me. There are tutors here too that can help anyone. It feels like a weight has been lifted of life my back from all of that work and now that there is people to help me out I feel like I can focus a lot better on my work and get good grades!
Sincerely (fill in your name here)
