When cleaning,
they watch people
throwing the trash that does not belong there into their own cleaning area,
but
the waste container is just a few steps away,

and they are constantly repeating the same thing every day.
Can you imagine how painful is the cleaning crew's heart?

They clean it today, but the trash will appear here again the next day.
Cleaning crews once look forward to the day when the streets are really clean,
But how long will it take, and when that day will come?

Or, whether that day really exists?
