I had an email from a very observant friend asking if I had suddenly become a Purdue fan because I am wearing a Purdue shirt in my profile picture.
The truth is, I didn't even realize I was wearing a Purdue shirt in the picture until someone else pointed it out. I'm not sure why my mother would have done such a cruel thing to me at such a tender age, but there's the photographic evidence.
For the record, I am not now, nor have I ever been, a Purdue fan.
(I am however a big fan of one particular Purdue engineering grad.)
