I guess now would be a good time to share this: I learned in R1 that there is no significance on who gets a call from whom and when. Don't despair if it takes a few days for someone to call you, and don't think you are any less special if you don't get a call from Dee (think about sheer amount of the time it would take for her to call every single admit). We tend to over-analyze things here...don't...just enjoy the fact that you got in to HBS
oh, and don't forget to say hi on the Facebook and LinkedIn groups!
