They are, as it were, ...

They are, as it were, train-bearers in the pageant of life, and hold a glass up to humanity, frailer than itself. We see ourselves at second-hand in them: they show us all that we are, all that we wish to be, and all that we dread to be. What brings the resemblance nearer is, that, as they imitate us, we, in our turn, imitate them. There is no class of society whom so many persons regard with affection as actors.
