I often think that my application is going to be sent to a certain professor at my #1 choice school (probably the only one who will understand the technical parts of my WS) who will then find HUGE mistakes/naivete in it and personally send scathing emails to the poor professors I got to write me letters of recommendation-- mocking them-- and then these LOR writers will contact me asking why I would "embarrass them like this?". And then, after being rejected all-round, I couldn't apply to graduate school again, even if I wanted to, because I've been blacklisted at my UG.
Then again, when thinking about my reply to this post, I've figured that the worst thing would be no response at all. Just nothing. As in "you're not even worthy of our consideration and you'll never even know what it would take to become one of us" type of thing.
