Hey man...the fact that you even suggested it is weird to me--I don't think I'd lie either way cause it's nobody's business, especially if they're not exactly winning life's lottery either (and who really ever does???)...
but that said, people are gonna talk about you/comment on your life/have an opinion about you in WHATEVER you do, so "giving them the satisfaction of not seeing you achieve one of your goals" is beside the point...You'll get in SOMEWHERE, do good work, graduate, and the be great at what you do. Then WHATEVER people say/think/do shouldn't matter...
Well, at least that's what I think...
