There is always one

There is always one person you have to hate during every stage of your life. Okay, maybe you don't have to hate him, but the person with the potential to be hated is always there. It may be a different person for each event, but there is always one. Right now mine is my Social Psychology professor. If I used phrases like cunt or ass clown or life-sucking bastard that is what he would be. But I don't use words like that.
