SORT OF LIKE QUADRUPLETS -- Miss Mary Zezas (left), assistant dean of women at Andrews University in Berrien Springs, attempts to learn who's who among the four freshmen coeds named Deborah Harris who are living in the women's residence, Lamson Hall, this fall. Left to right behind the desk are Deborah Anne Harris, nursing major from Brookfield, Illinois; Deborah Anna Harris, physical therapy student from Mt. Vernon, Ohio; Deborah Jean Harris, physical therapy student from Merritt Island, Florida; and Deborah Faye Harris, history major from Detroit, Michigan. True enough, they don't look alike, but getting phone calls, amil, and messages to the right Deborah Harris may be an interesting experience for dormitory personnel
