Human beings cannot live alone, by this reason, we are called social animals.
Animals also cannot live alone because they cannot feed themselves.
We are companions because humans need animals and vice-versa.
The essence of nature is harmony.
Consideration, cooperation and coordination are the three core columns of harmony.
We are the same destiny union who depend on each other.

They know each other well so they can tell what each other is thinking.
They are scared of each other's death because they cannot live without one each other.
