15 years ago, I thought that I was a sky-reaching tree;

15 years later, I realize that I am nothing more than a tiny grass.

15 years ago, time was the only thing I can waste;

15 years later, I can waste anything except for time.

15 years ago, youth was unrepentant to me;

15 years later, youth is far away from me.

15 years ago, I felt proud that I can play with life;

15 years later, I am trapped in the game of life.
