Everyone knows about the obvious and common forms of jealousy like wealth, fame, and social status.
But what I find interesting is the subtle and advanced forms of jealousy.
Like Roy Keane, the black and white thinking hardened general standard setter being jealous of the fun and freedom Dwight Yorke could have.
Or the bully being jealous of the obvious signs of love and care the small kid shows.
Or the troops who have been held to such high standards of discipline for so long witnessing one soldier being shown unknown levels of leniency.
