After Helen Gahagan Douglas was elected as a Democratic representative in 1944, news outlets spread rumors of a vicious rivalry between her and Republican congresswoman Clare Boothe Luce; one headline read helen vs. clare: torch vs. icicle. “For reporters short of real news,” Douglas complained, “it was a simple day’s work to speculate that we would claw at one another.” The women resolved to avoid giving fodder to such baseless stories by never discussing the same subject on the same day.

“I have personally watched and studied a jealous baby,” Saint Augustine reports in his Confessions. “He could not speak and, pale with jealousy and bitterness, glared at his brother sharing his mother’s milk.” Regarding the baby’s sinister intent, Augustine contends that “it can hardly be innocence,” when the milk “is flowing richly and abundantly, not to endure a share going to one’s blood brother, who is in profound need.”
