The introduction (or "orientation", as it is called by the university) is a time without worries. You can get to know your new city, your fellow students and have a great time doing so. Most new students become members of Thalia, because of the awesome benefits it gives them. During this time, the introduction committee tries to place Thalia in the most favorable of daylights. They also try to lighten the workload of the mentors that actually do the hard work of accompanying the new students. Mostly by drinking their beer for them. No problem.
