One of the things that I love about your fics is that you have to re-read them to get the whole thing, because you transition from funny to sad to something in between so quickly that it's easy to miss things. I was still laughing about:
Dean was watching Sam make wary eyes at the ducks, so he wasn't paying attention.
and frankly, ducks can be very threatening... and I totally missed the weight of this amazing line in the first read:

Every now and then - not often - a lie hurts a little, and this one does. But in his mind Sam will get a chance to finish Stanford because all that work should never go to waste.
This part is beautiful for so many reasons, one being it just is. The wording is so true and painful. One thing that everyone seems to write is that Dean feels negatively about Sam's time at Stanford, and that he doesn't want Sam to ever go back. I love how this little part of Dean's internal monologue speaks volumes about what he thinks about Sam at school.

Your Dean-voice and the interactions between the brothers is, simply put, amazing.
