The following text is adapted from Oscar Wilde's 1895 play The Importance of Being Earnest.

CECILY: Have we got to part?
ALGERNON: I am afraid so. It's a very painful parting.
CECILY: It is always painful to part from people whom one has known for a very brief space of time. The absence of old friends one can endure with equanimity. But even a momentary separation from anyone to whom one has just been introduced is almost unbearable.
