Many of my emotional scars have healed, leaving only the memory. I can see how some might be not only ugly scars, but might still be sensitive or even painful.
But if we wore our emotional scars for all to see, there might be a new standard of beauty, which reflected empathy for some of the deeper scars. Since they would be on display for all to see, there would not be the stigma that there seems to be with visible physical scars.
