The chariest maid is prodigal enough,
If she unmask her beauty to the moon:
Virtue itself 'scapes not calumnious strokes:
The canker galls the infants of the spring
Too oft before their buttons be disclosed,
And in the morn and liquid dew of youth
Contagious blastments are most imminent.
-- William Shakespeare (1564-1616), Hamlet
-- Act i, Sc. 3
