I only remember a little of what I learned during my first days as a University of Wisconsin-Madison freshman in the late 1990s. The vegetarian chili sold in the student union’s bar tasted of beans and sawdust. The most important unwritten rule required freshmen to take blurry Polaroid pictures of ourselves seated atop the lap of the Abraham Lincoln statue at 2 a.m. And if we wanted to protest anything, we could.
