“One noteworthy study suggests that people who suppress negative emotions tend to leak those emotions later in unexpected ways. The psychologist Judith Grob asked people to hide their emotions when she showed them disgusting images. She even had them hold pens in their mouths to prevent them from frowning. She found that this group reported feeling less disgusted by the pictures than did those who'd been allowed to react naturally. Later, however, the people who hid their emotions suffered side effects. Their memory was impaired, and the negative emotions they'd suppressed seemed to color their outlook. When Grob had them fill in the missing letter to the word "gr_ss", for example, they were more likely than others to offer "gross" rather than "grass". "People who tend to [suppress their negative emotions] regularly," concludes Grob, "might start to see their world in a more negative light." p. 223”

“It's as if they have thinner boundaries separating them from other people's emotions and from the tragedies and cruelties of the world.”

“The highly sensitive [introverted] tend to be philosophical or spiritual in their orientation, rather than materialistic or hedonistic. They dislike small talk. They often describe themselves as creative or intuitive. They dream vividly, and can often recall their dreams the next day. They love music, nature, art, physical beauty. They feel exceptionally strong emotions--sometimes acute bouts of joy, but also sorrow, melancholy, and fear. Highly sensitive people also process information about their environments--both physical and emotional--unusually deeply. They tend to notice subtleties that others miss--another person's shift in mood, say, or a lightbulb burning a touch too brightly.”

“Faces may be hard to read because humans are complex social animals that have learned to suppress the display of emotions for various reasons. It is often inappropriate to show negative emotions like hatred and contempt in public, so people go about wearing socially acceptable faces rather like masks.”

“All emotions, even those that are suppressed and unexpressed, have physical effects. Unexpressed emotions tend to stay in the body like small ticking time bombs—they are illnesses in incubation.”

“People tend to think that hate is the most dangerous emotion. But love is equally dangerous,” Will said. “There are many stories of spirits haunting the places and people who meant the most to them. In fact, there are more of those than there are revenge stories.”

“A clear understanding of negative emotions dismisses them.”
