The biggest addiction in college: skipping class. Part of my job as an Admissions Advisor at Eastern Washington University is to give presentations to visiting middle and high school classes that come to see what a college campus is like.
The Athenian Agora. The Agora of Athens was the center of the ancient city: a large, open square where the citizens could assemble for a wide variety of purposes. On any given day the space might be used as a market, or for an election, a dramatic performance, a religious procession, military drill, or athletic competition.
The agoras of the ancient Greek city-states were open areas for people to assemble for anything from military purposes to political or commercial ones. Ancient Agora is the most popular of its kind, thanks in part to its historical significance.
