Econ 305 was not the students' favorite class. Boring, in the hottest building on campus, and for 2 hours at a time. Sure they 'needed' it for their degrees, but they really wished they'd gotten a teacher that was less of a hardass. They longed for Econ 101's professor, who didn't take attendance and gave them open book tests online. Those were the days.
But now, it was Miss Rin. She was stern, sarcastic, and not up for jokes or prattling in class. It was give answers when asked or shut up. At least at the start of semester. As the weeks dragged on, the students began to notice her softening up. A phrase chosen very carefully.
