Where does much of the world's sorrow come from?

Question

Maude: What kind of flower would you like to be?
Harold: I don't know. One of these, maybe.(points to a huge bed of daisies)
Maude: Why do you say that?
Harold: Because they're all alike.
Maude: Oh, but they're NOT! Look. See, some are smaller; some are
fatter; some grow to the left, some to the right; some even have lost
some petals. All kinds of observable differences! You see, Harold, I
feel that much of the world's sorrow comes from people who are *this*,(points to one daisy)
yet allow themselves to be treated as *that*. (points to the huge bed of daisies)
