Exception

How happy is the blameless vestal's lot!
The world forgetting, by the world forgot.
Eternal sunshine of the spotless mind!
Each pray'r accepted, and each wish resign'd;
..
Far other dreams my erring soul employ,
Far other raptures, of unholy joy:
When at the close of each sad, sorrowing day,
Fancy restores what vengeance snatch'd away,
Then conscience sleeps, and leaving nature free.

Alexander Pope
