I often find that many things are constantly changing.
Whenever I look back, I will find that many things have changed and become blurry. I don't know what kind of physical environment it was under to evolve some squeaking sounds similar to those made during chemical reactions. I know it is changing, and those things that were originally clearly visible are evolving in directions we cannot predict at our irreversible speed of light.
And no one knows what its passing has left behind. Time is such a wonderful thing. It can drastically reverse a person's growth trajectory in an instant, and it can also invisibly consolidate those so-called beautiful things. But all this has become blurry in my eyes.
