Sherri would be an RA, most likely. She would distract homesick freshmen with stories and try to play big sister to everyone in the building, whether they wanted it or not.
Theo would be the fashion major who wears the strangest outfits and who everyone suspects knows where to get the really good shit even though he's just weird and energetic, not on drugs. That or he'd be that bum that hangs around campus even though he's been escorted off by security/Luther a million times.
