The tragedy of the commons isn’t that most people take such good care of the commons. I bet people see your tidy walk and feel guilty about messing it up.

I've observed people picking up trash there, so I know it happens. I have a trash can right by my entrance so it's easy to throw stuff away properly.

Sometimes people do feel guilty dropping stuff, but usually only if they notice me watching them do it.
