In the depths of every heart, there is a tomb and a dungeon, though the lights, the music, and revelry above may cause us to forget their existence, and the buried ones, or prisoners whom they hide. But sometimes, and oftenest at midnight, those dark receptacles are flung wide open. In an hour like this, when the mind has a passive sensibility, but no active strength; when the imagination is a mirror, imparting vividness to all ideas, without the power of selecting or controlling them; then pray that your griefs may slumber, and the brotherhood of remorse not break their chain.

Nathaniel Hawthorne (1804-1864) American writer
