He thanked my wife and me in the letter. He also wrote how he will study hard to get a good grade in middle school. He said he will get at least 450 points in five main subjects.
The reality is that.... I shouldn't say anything about that. He is about to graduate from middle school. He did not study well, but he was good at sports club and I really proud of his effor to the club.
I have a little hope that he finally figures out the importance of studying for his future career in coming three years of high school days.
