Jealousy in romance is like salt in food. A little can enhance the savor, but too much can spoil the pleasure and, under certain circumstances, can be life-threatening.
Our faith in others betrays that we would rather have faith in ourselves. Our longing for a friend is our betrayer. And often with our love we want merely to overcome envy. And often we attack and make ourselves enemies, to conceal that we are vulnerable.
Who loves the golden mean is safe from the poverty of a tenement, is free from the envy of a palace.
[Lat., Auream quisquis mediocritatem deligit tutus caret obsoleti sordibus tecti, caret invidenda sobrius aula.]
