Okay, Hillsdale is pretty small, so I don't get all excited when I see other Greeks.... I know them all.
But, in my classes:
Methods (6 people): 1 Kappa
Shakespeare's Tragedies (12 people): 1 Kappa, maybe an SAI (they don't wear letters often, so I'm not sure which girls are actually in SAI)
American Novel (about 15 people): 1 Pi Phi, 1 Pi Phi who went alum, 2 Kappas, 1 SAI
SR (5 people): 1 Chi-O new member
Practicum: 1 Pi Phi, 1 Chi-O, 1 SAI, 1 Kappa (and I'm not sure what else.... That class only "meets" once a month)
