Now that I've collected myself somewhat, I can write this.
First of all, congrats to Peter, WashU is a great school. I know I would have loved to go. It's funny how schools that have already rejected me are actually the ones I spent most time tailoring my SOP to. I had to think hard to remember what I wrote for my waitlist and admission (which is my safety). I came home from a long day to find my WashU rejection letter waiting for me in my inbox and it almost snuffed the life out of me, but just briefly. I suppose it was one of those schools (irresponsibly quoting other posters on this board) that was all "rainbows and cupcakes" for me. With the hope of dancing on the rainbows and (at the same time) devouring numerous cupcakes taken away from me, I feel a little barren.
However, I will be alright. The road through academia is long and winding and I'm just getting started. I will have other chances, other opportunities, and it doesn't all have to boil down to getting in a certain school or not. Finally, I can rest easy for now...and good luck to all, it's not over until the fat lady sings!
