    I know a woman who tries hard to be a good custodian (保洁工). I pass her every day after school as she pushes her cart down my hallway. Of course, she is my building’s cleaner.

One Tuesday morning I came into school and saw a ______ on my desk from my custodian. It seemed that some unbearable first year students had damaged the bathroom in a particularly disgusting way and she had been ______ to clean it. This took ______ than she had expected. She had left the typewritten note on my desk to ______ for not being able to clean my room as she was ______ to do.

At the beginning of the period, I shared her note with my first period ______. When I mentioned that our custodian had apologized to us, their first ______ was to volunteer to seek out and beat up those first year students for making our custodian have to clean up their ______. It turned out that just about all of my students also knew our custodian by name-all of them responded with smiles and ______ for a long time about this time or that time when she’d ______ each of them in the hallway. That she felt she needed to apologize ______ a strong reaction from many of the kids.

As the class period was about to end, I asked them to ______ the floor like I do every period and thanked them for picking up any garbage ______ it wasn’t theirs. My entire class disappeared; they each disappeared instantly ______ their desks to pick up those annoying tiny pieces of paper that ______ so easily from notebooks. One girl made a(an) ______ that I later used with my other classes: “Her job might be to clean the room, but she shouldn’t have to clean up ______ us. There’s a difference. “

I believe that people know the difference between right and wrong. I believe that people appreciate it when others ______ take care of them. And I believe that people, even adolescents who are not quite yet mature, appreciate it when they see someone who takes ______ in her work. Sometimes we need a ______ of the things we take for granted... things like a good custodian to take care of us.
