The student union is one of the most inviting places on campus. Maybe that's because there are people paid to invite you to the ASU's events, either way it is designed to have an appealing environment. Whether it's the design of the circular chairs where no one can actually face each other, to the balcony right next to the "Blue Coyote" formerly known as the pub, it has that look, which is meant to attract, however debatable its actual efficiency is.
The student union is also where most of college discourse goes on. People meet durning their breaks, or when they're finished with their classes and hang out with friends there. It's a daily hang out spot for greek life and the lonely freshman that just wanders around aimlessly with 2 hrs to kill before their next class. Here anything is an open subject, whether it's how hot that person sleeping on the couch is, to the next mayor or even just stupid talk that gets forgotten in less than 3 minutes
