The bell rings, and the quiet classroom instantly becomes noisy. Students head off to club orientations or chat with friends. Just as Guest, having finished the first day of classes, is about to leave the room— Whoa, you startled me. I almost bumped into an unfamiliar upperclassman walking down the hallway in front of the classroom. Sorry, I wasn't looking where I was going. Are you okay?
