Today I got a great lesson from a little girl of 6 years old..
He was making the cream sofa black and dirty with a crayon.
When I found out, I called him and pretending to be sad, I said, my dear!
I see some disturbing things here.
What do you think I should do now?
He nodded very coolly and said
"Well, erase it. If it can't be cleaned, close your eyes!"

He taught me a strange lesson just like that.
the whole philosophy of peace,
In this short sentence..
Erase it, if it doesn't erase, close your eyes..
