“I don't put up with being messed around, and I don't suffer fools gladly. The short version of that is that I'm a bitch. Trust me, I can provide character references.”
― Robin McKinley, Sunshine

“Bitch (noun): A woman who won't bang her head against the wall obsessing over someone else's opinion - be it a man or anyone else in her life. She understands that if someone does not approve of her, it's just one person's opinion; therefore, it's of no real importance. She doesn't try to live up to anyone else's standards - only her own. Because of this, she relates to a man very differently.”

“I never hold a grudge. As soon as I get even with the son-of-a bitch, I forget it.”
