I remember reading a story decades ago in which the basic rule of what is permitted was reversed. I am accustomed to being permitted to do anything that is not prohibited. In this story, people could do nothing unless invited.
The example I remember from the story was that there were no longer signs prohibiting you from walking on the grass. Instead, you were prohibited unless there were signs inviting you to walk on the grass.
I am unsure of the genre, but suspect it might have been sci-fi. Ring a bell for anybody? Looking for name of story and/or author.
