I was originally wait listed for grad school. Later that same week the dean of the school gave me this overly friendly phone call to personally let me know I was admitted. At first I figured they were just really friendly there…
As it turns out, coincidentally an executive of a large company who just happens to share my last name, though unrelated to me, made a significant donation to the school the same week I got my wait list letter.
Later I saw the donation mentioned in a newsletter. I never told anyone until after graduation. Everyone in admin was really nice to me there.
