There are a great many strange things in the world...
But no matter how odd...
How incredible something may be...
If a human does not touch it...
If a human does not see it...
If a human is not involved with it...
It is simply something that happened.
Simply a matter that will fade with time.

Humans.
Mankind.
Homo sapiens.

Humans are the most profoundly mysterious living things in the world!

Family is other people.
No matter how close you're related by blood... No matter what your relationship may be...
Anyone other than you is not you!
