Citing a lack of opportunities after a year in the outside world, Jacobean drama student Mark Griffin has decided to return to school to pursue a master's degree in his major subject, and a potential mate. 'My main ambition is finding someone I actually care about right now, and the opportunities just aren't there in the corporate world,' Griffin, 24, said Tuesday from the University of Michigan's Shapiro Library. 'Or, I may just still have a lot to learn about women, so, either way, grad school's the right choice.' Griffin declined to comment on the fact that, in his first six years at college, he was employed in only two gainful romantic positions.
