Dear Grandpa and Grandma,

Thank both of you for helping me and taking care of me. I will try to find a way to repay both of your kindness as fast as possible as Grandpa is already 50+ years old and Grandma is already 50+ too.

I know that i may not be able to repay both your kindness as i am only 11 this year. I will strive to get good marks in exams and save money then maybe i can bring both of you for vacation somewhere that you like to go. Maybe if i save more money, i will buy both of you a big house. I wish both of you the best of health.

Yours Truly,
Ong Teng Jun
