theory of relativity

Painful and painful feelings will last forever...
Happy thoughts pass in an instant...
What is time?
I wonder if it's a prank from God...
Even after passing through a long, dark tunnel, light shines through.
And then, a dark night begins again.
Even if you keep running believing that it will come someday,
Will there ever come a day when I truly want to move on to tomorrow?
We are just a small piece in a big miniature garden.
