I loathe a friend whose gratitude grows old, a friend who takes his friend's prosperity but will not voyage with him in his grief
Euripides
Love must not touch the marrow of the soul. Our affections must be breakable chains that we can cast them off or tighten them.
Euripides
Those who are held wise among men, and who search for the reason of things, are those who bring the most sorrow upon themselves
Euripides
