I could stand on my head and do cartwheels and some students would still not pay attention, blame me for their shitty marks, and complain that they were bored. Not everything in life is meant to be exciting all the time. That said, I work hard to keep my classes interesting but the idea that everything should be entertainment is an insidious idea whose time has come and gone. Some things are work, ya know? And occasionally work/effort pays off.
