Probably not... it was ten years ago. But I told them that I've been harboring a huge guilt because I borrowed and neglected to return one the professor's books back then.
I was supposed to work with her on a research project on Software-based Neural Networks... for publication and everything... very cool project, and an honor to be asked to do it. But that was right about the time I had to quit the program... and never returned the book and software that we were gonna start the project with. It's been nagging at me for all these years to now.
I really regret not getting to do that. Keep in mind that this was about 1995/96... and "virtual" neural networks was a really cutting-edge concept back then. Still is, in lots of ways.
Heh...is this book gonna come back to haunt you like Corin's wedding pictures?
