Life is like a loosely written book. You start a chapter with great expectations, but before you even begin, you find that there are too many surprises that you cannot predict. You cannot predict the next chapter after writing the first chapter. You can never write a prologue that is close to the theme in advance, let alone an extravagant theme outline. But the most ordinary life and the most natural fate always use all kinds of unexpected and reasonable jokes to make one joke after another with everyone, no matter what the onlookers think, it is difficult for the person involved to laugh it off. The most annoying thing is that fate always thinks of itself as humorous and friendly.
