Dear Martin,
How are you doing recently? I’ve been missing you so much since you retired.
On behalf of all my schoolmates, I’m writing to express our deepest gratitude for your devotion to the students of our school. We are more than grateful for all you did for us over the years.
The memories are still fresh. So inspiring and humorous were your classes that we were able to learn English with interest and fun. Actually, not only did we learn the language but also our critical thinking skills and creativity developed in your class. We do appreciate it!
Although you have retired, those memories are unforgettable. As your students, we all hope you will enjoy your life after retirement. We wish you happiness and health in the years to come!
Best wishes,
Your students from Chengdu No. 7 High School
