Interviewer: Thank you for talking with me today. What time does your work usually begin?

Cleaner: On weekends, I start at six in the morning. The first train is already busy, so we have to move quickly.

Interviewer: What is the hardest part of the job?

Cleaner: The hardest part is noticing small things. A clean train is not only about the floor. We check seats, windows, handrails, and the space under bags.

Interviewer: Do passengers ever thank you?

Cleaner: Sometimes. One child once said, "The train smells like morning." I still remember that.

Interviewer: What do you want students to know?

Cleaner: Small habits matter. If one person takes their trash, the next person feels more comfortable. A clean place is made by many quiet choices.

Interviewer: That is a nice way to think about public spaces.

Cleaner: Yes. We clean the train, but passengers help keep it clean.
