There were three of us in my grade named Jennifer. Two of us had the same birthday. I always got bummed out when they did the birthday announcements and I'd get all excited thinking my friends put one in for me, but when they got to the last name it was the other one. SHEESH!
I spell it Jenn these days. There are 8 people with the same first and last name as me at my job. I get emails intended for the one in the legal department all the time.
