I don’t know why—it’s just that—I don’t know—they’re not kin."—Surprising word, I think to myself never used it before. Not of kin—sounds like hillbilly talk—not of a kind—same root—kindness, too—they can’t have real kindness toward him, they’re not his kin -- . That’s exactly the feeling. Old word, so ancient it’s almost drowned out. What a change through the centuries. Now anybody can be "kind." And everybody’s supposed to be. Except that long ago it was something you were born into and couldn’t help. Now it’s just a faked-up attitude half the time, like teachers the first day of class. But what do they really know about kindness who are not kin.
