First day of class students are normally anxious, some to the extent of being, shall we say, freaked out, as Chic put it in Le Freak (Chic) which was released in 1978.
Between my no late work policy, my "Damn the torpedoes" attitude but self-effacing humor, after awhile students are on the fence. And ask themselves, Should I Stay or Should I Go? (The Clash), released in 1981.
And finally, after my first lecture (more like a vignette) they will understand how I will be able to lead them to the Promised Land and so they will raises their voices and collectively proclaim, Show Me The Way (Peter Frampton) released in 1975.
