In my dream during my senior year of high school, I dreamed that I became a boy and spent the whole day playing in an amusement park with an unknown boy.
During those three seconds on the jumping machine, he gently touched the light and shadow on my cheekbone with his fingertips.
He said: "The face when light and darkness intersect is evidence of the passage of time."
Later, when I woke up from the dream, I remembered the intersection of light and dark in every sunset.
I finally understood another sentence he said——
Some flowers bloomed, but the rain that was supposed to come never came.
And the thunder I owed him in spring later fell on every rainy day I waited for.
Concept: Time will steal everything, but you can learn to feel its shape before it is stolen: light and darkness, thunder and waiting are all its names.
