So, some back story, I emailed a professor i had last year at a different university (1000 miles away from where I am now...) to ask if you could write me some letters of recommendation. he responded the next day saying he'd be happy to. I responded the next day giving him all the information he needed to write the letters.
then i hear nothing from him for a couple weeks. it was ok, since I emailed him over a month in advance of when my applications are due. i decided to email him again and ask if he received everything, etc. then, after another week or so, I emailed him again and asked if he was still planning on writing me recommendations. still no response.
So now, with about a week and a half till the due date, i build up the courage to call his office... and he says that he's been too busy. great. so much for my applications, then, huh?
