Suppose this is your second time applying to grad . . . and your second time getting rejections (or presumed rejections) across the board. All your old professors are baffled, outraged, and depressed by turns. And you're really tired of the pity and the annoying observations that "you're the perfect candidate, I don't understand, etc." You've reminded them of every reason why it's hard to get in, the match must not have been perfect, funding's scarce, application numbers are up, adcoms care almost only about your writing sample and whether or not their profs want to work with your kind of research for the next 7 years -- and yet still your old profs insist "I don't understand." It only contributes to your dejection (from which you'd really rather move on), and you're mildly concerned that they're going to start thinking you have a felony keeping you out of grad.
What do you do?
