If a man steps on a stranger’s foot
In the marketplace,
He makes a polite apology
And offers an explanation:
“This place is so crowded.”
If an elder brother
Steps on his younger brother’s foot
He says, “Sorry.”
And that is that.
If a parent steps on his child’s foot
Nothing is said at all.
The greatest politeness
Is free from all formality.
Perfect conduct is free of concern.
Perfect wisdom is unplanned.
Perfect love is without demonstrations.
Perfect sincerity offers no guarantee.
— Chuang Tzu
