i don't remember exactly what it said and i don't have it here with me, but it was something along the lines of "it is so difficult to reject so many extremely qualified applicants. we take comfort, however, in the fact that we know you will end up at another great top law school." it was kinda longish, and generally just very nice.
and re: columbia -- i don't know
didn't get anything today, but im trying not to worry about it. i'm already stressed out enough looking for my harvard deferral every day in the mailbox (or rather, having my mom look for it and call me).
