In the story, a lousy woman says to the police with the sin heart:
"In my life time, I have never seen a thorough villain or a heartly
saint. No one is purely white or completely dark. It's the grey which
dominates the all of us. People are like their souls....you are with a
grey heart representing splendidly grey just like us..."
Some people are shaped with the dark spirits and some people's color
tends to be white.
That's what the story wants to show us and tells us the myth of the
human beings.
Frankly speaking, when I was a child, I knew how to grab my parent's
attention and gain their concentration from other brothers or sisters.
And I just didn't need to find out the skills which were likely easy to
be found if the parents always gave their preference to some of the objects.
Thus, is it possible that my tendence is dark side?
Even when I am grown-up, I would do some favor to the strangers or
donate some money to the beggar and help the stray dogs home.
So does it mean that I am a thoroughly white towards others?
I just want to remind that the book's content is all about the
grey part of the human soul and I just want to let you see
what we may be as we're all grown-ups.
Hopefully it will be fun.
