The private kindness of one individual towards another; a petty, thoughtless kindness; an unwitnessed kindness. Something we could call senseless kindness. A kindness outside any system of social or religious good. But if we think about it, we realize that this private, senseless, incidental kindness is in fact eternal. It is extended to everything living, even to a mouse, even to a bent branch that a man straightens as he walks by.
