Studying for Waters is just a waste of my time.

1. What are the four causes for the fall of the Roman Empire and how did each contribute to the collapse of the empire?

For one thing, the fact that I'm his first but you're his second gives him a bit of an advantage.
For another, it doesn't help that everyone's liked him, which helps them understand why you like him, too, whereas nobody's ever liked someone like the other him.
It doesn't help that I just referred to him as the other him.

(Germanic invasions, corrupt officials, lack of nationalism/patriotism, and heavy taxes.)

2. What was the Peloponnesian war fought over? What was the outcome? How did this war lead to the end of the Greeks?

You always wished you had it like me. Now you've got your wish, and honestly I'm happy for you, but quite frankly I'd rather like it if she stopped referring to you two as the new us.

(Conflict between Sparta and Athens - Sparta resented Athenian domination. Sparta and Persia joined forces and captured Athens, whose economy eventually recovered, making them dominant again. However, democratic government suffered, as well as the spirit of Athens.)

And the rest...is history. No, I just don't feel the need to study more for Waters.
