I'm happy to be one of the 'ant workers'

I used to work as an administrator, and when I retired in 2016, I began visiting the riverbank because a lot of retirees do physical exercises there.

I was curious when I saw groups of people - usually five or six at a time - picking up garbage on the riverbank. I was very impressed when I learned that they were volunteers rather than paid sanitation workers sent by the government.

The garbage stank, but they didn't seem to care. Moreover, they asked for no return, financial or reputational.
