I want to quit my job and go back to my own city. Why do leaders tell their subordinates that I am active, not lazy, silent, self-respecting and anxious?

Maybe it's because the leader thinks you have done well during your work and are responsible for your work. The leader hopes that you can finish the work smoothly before you leave and leave a good impression on other employees.

Your leader may be satisfied with your performance and hope that other employees can learn from your performance. The leader may tell his subordinates that he hopes you can continue to behave well after you leave.

Your leader may think that you are a trustworthy employee and willing to contribute to the company. They may want the company to continue to benefit from your skills and experience after you leave.
