The most intense feeling I have when I find out a stranger gets into my top school is curiosity (about their stats). Other than that, I'm generally an apathetic zombie.
However, if it's someone I know personally, my reaction is pretty melodramatic. For instance, I recently found out that an extremely vacuous acquaintance of mine has just been admitted to my dream school. I'm currently going through a stage of self-hatred and my friends are baffled by this, since I haven't been rejected...yet.
I've spent the past few days sulking and eating ridiculous amounts of Nutella.
