<p>I don't think that there is anything wrong with staying on the waitlist if you have the right attitude. Speaking from experience, I don't care if it is a polite rejection--a waitlist is a lot easier to stomach than a rejection. I plan to stay on the waitlists that I was offered (Brown and Columbia), although in reality I doubt Columbia will take anyone (and certainly not me, at any rate), and I don't really know if I will want to go to Brown in the slight but possible chance I get off the waitlist. Being that I have already started to move on, I don't think I am in danger of being too attached to what are probably essentially rejections.</p>
