I have been accepted at Yale, Columbia and Chicago and I am waitlisted at Princeton and MIT. Princeton is my first option and so it would be in my best interest to tell you to do to Stanford. However, I do think that based on your interest, Princeton is a better fit for you (of course Standord would be great as well). Anyways, hope that I may actually receive an offer from Princeton and we both can attend.
I think I will go to Yale.
