Letter 5. 

Dear Sister-in-law,

I am writing this letter to simply say thank you. I want you to know how much I appreciate having you in my life. Your support and understanding have meant a lot to me.

Do you remember when you helped me with my school project last month? I was so stressed because I had to design a model of the solar system and I had no idea where to start. But you stepped in and taught me all about the nine planets, their sizes, and their distances from the Sun. 

You told me that Jupiter is the largest planet with a diameter of 86,881 miles, and that the Earth is the third planet from the Sun, approximately 93 million miles away. With your help, I not only completed my project but got an A+!

Without you, I wouldn’t have been able to win the school science fair. That’s a fact! You not only helped with my project but also spent a total of 20 hours over two weeks just helping me understand and learn about our solar system. I am so grateful.

Thank you for always being there for me. I am really lucky to have a sister-in-law like you.

Sincerely,

[Your Name]
