Time Passages

I think this is a brilliant song and I think Lewis Carroll would have liked it; maybe even some scientists and William James too. And I'm willing to bet there is a mathematically equivalent expression of it. It's kind of like each decision you make veering off to a new direction for your life path like the tracks of that last train he's going to ride. You could say it's like Robert Frost's The Road Not Taken except it isn't because, the chooser goes both ways on alternate planes.(I didn't come up with this alternate universe idea but, I can't remember the scientist who did.) But, I do say, there is no solid past or memory as it becomes as option filled as the future and as he reaches his hand as the girl comes towards him he once used to know, he's all alone because his track and her track crossed again but on different planes so they know each other yet never met because, it's only time and like night flows like a river.
