No matter how strong a person is,

he would still have his weakness.

No matter how strong a person is,

he would still feel emptiness.

What makes the different is the extent and duration.

No one on this world is able to survive alone.

No one.

This is the nature.

No matter what makes us to developed into the system of this kind, i believe, there is a purpose for its existence.

All those who doesn't have this set of emotional control system,

had already extincted long time ago.

The one which exists, we,

are dependant on this useful function.

But i dont understand,

why?
