Dear Grandpa,
How are you these days? I miss you very much. It has been two months since we last saw each other. I hope you're healthy and happy.
Every day at school, I learn new things. My favorite subject is English because it's fun to speak and write in another language. At home, I help Mom with some housework like cleaning my room and watering the plants. Dad says I'm becoming more responsible.
Last weekend, I went to the park with my friends. We played games and had a picnic. It was so much fun! Please take care of yourself, Grandpa. I can't wait to see you soon.
Love,
Your grandson, Tom
