An anonymous rant found on craigslist:

The third rule (related to #2) is never rate your pain a 10/10. 10/10 means the worst pain you could possibly imagine. I’ve seen people in a 10/10 pain and you sitting there playing tetris on your cell phone are not in 10/10 pain. 10/10 pain is an open fracture dangling in the wind, a 50% body surface deep partial thickness burn, or the pain of a real cerebral aneurysm. Even when I passed a kidney stone, the worst pain I had was probably a 7. And that was when I was projectile vomiting and crying for my mother. So stick with a nice 7 or even an 8. That means to me you are hurting by you might not be lying
