And someone reminds you about the point you left ten minutes ago. These lines suggest hypertext theory. The reader like Frost's protagonist has to make the choice and no two readings will ever be the same and return is also doubtful. I say linear is unnatural because when I plan something in linear fashion I never follow it. The shortest distance between two points may be a stright line but in life that just doesn't happen.
Life is more like hypertext than it is linear.
Enough for now. The example and the kids' work aren't perfect, but they are close. The kids found they needed to change things to get the linking right. All of a sudden form dictated. Each haiku has a link to the other four haiku, so the reader chooses the next haiku to be read by clicking on a word, which will take the reader from haiku to haiku.
