Jen and Jan are dorm roommates and they tend to do everything together. They wake up at the same time, they eat their meals together in the cafeteria, and they even happen to be taking the same psychology course this term. Both consider themselves to be conscientious students. They go to every lecture, they take notes on the lecture, they read the book as assigned, and they take notes on the book. So far, you can see they are in perfect agreement.
