Sympathy is what you have for someone after they die, pity you have for someone when they don't have a date to the biggest dance of the year. Empathy is what I do to you when you judge me. Envy is having pity on yourself. Can you discern the rest for yourself?
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.]
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.
