You know what I hate?

Douchebags.
There's this guy that works at my work, who is a complete douche. He walks around, and thinks he's hot shit just because he has shaggy hair, and was probably into sports in high school. But in reality he's just an arrogant jerk who isn't very attractive. He dropped a bunch of boxes on the floor today at work, and John and I laughed at his stupidity. Then I said he should be fired, in a Donald Trump-ish tone.
Then there's people who I automatically assume would be douchebags from first glance, who prove otherwise down the line. If I ever assumed you were a jerk, and you turned out to be one of the few that actually turned out to be different, I'm sorry. I know it doesn't make a difference, but I felt the need to say it.
