Ram and Shyam are roommates. Their professor encourages collaboration on homework. Shyam relies on Ram to explain the problem to him, show him the approach and the homework he plans to hand in. Ram now feels that Shyam is taking advantage of him. Should Ram demand that Shyam do more of the work, even if it takes him twice as long? If Shyam doesn’t do his share of the homework, should Ram stop their joint homework, or even tell the professor that Shyam just copied Ram’s homework for each class?
