I know they get paid to clean up but being a caretaker or cleaner isn't the most glamorous of jobs and they deserve respect and thanks for the hard 'unskilled' work they do. I remember being at school and kids leaving a mess on purpose claiming they didn't have a responsibility to clean it up 'cos the cleaners will do it, they get paid to', totally taking them for granted. I also have a neighbour who's lovely and works hard as a cleaner. It was little things like that that inspired this one.
