Another Pastiche, this one based on Mark Collie's "Even the Man in the Moon is Crying" (oooh, country!) about Trelawney and her ways of greeting a class. The "Gryffindor girls" part refers to the Lavender Brown and Parvati Patil type of Gryffindor girl, not the Hermione type (though she certainly sighed at Trelawney's ridiculousness, and snorted, and huffed, and scoffed).
