I remember when I was applying to graduate schools I was waiting to go to my last (fourth) recruitment interview, but I was pretty sure I wanted to go to the third school I had visited. Well I wasn't back for more than a day from the last recruitment trip when I called up that third school to ask them when I should show up and what paperwork I needed to fill out... it wasn't until about two years later that I realized I couldn't remember receiving an official acceptance letter or phone call from them...
