Teaching in the month of May is like being Sisyphus, a Greek legend of a man condemned forever to push a boulder up a hill, only for it to roll to the bottom before he reaches the peak, and to roll it up again.
I'm pushing my students up that hill, all 85 five of them....Do your warm-up! be in your seat, do your work, your homework, study, etc...and like any motion on a rock face, some are falling off like rubble...but I keep teaching...keep pushing them up that hill.
Because, like Sisyphus, there is a a heroism in accepting an impossible challenge. Even when it's frustrating and everything seems futile, as Camus said about Sisyphus, "All is well."
