Person: Omg, I hate her. She's sucha bitch and a slut.
Me: What have she ever done to you? Why are you insulting her?
Person: Nothing, but she's still a slut.
That's the thing about people these days. They automatically assume shit about a certain individual when they don't even know them. Why would you hate someone if they've never done anything to you? Just because everyone around her hates her doesn't mean you have to play along with it.
