The people I "knew of" in college, I would not have been able to provide their motivations for taking classes. You have to be a bit closer to them to know why they are taking something. I could guess at their motivation, which is what I suspect you have done.
Anyway, you missed a great learning opportunity in an area where you thought nothing useful was to be gained. Music theory is a fascinating topic, having knowledge of why Mozart chose to voice a section of a sonata as he did is very enlightening. Seeing the independent lines of a Bach fugue, and understanding how it got put together is just damn interesting, IMHO.
I was just teasing you about the whole slacker thing anyway, no harm intended. Your negative comments about the study of music theory earned you that teasing.
Also, I was not guessing at some people's motivation for taking the class. It was widely known that for an easy A, one could take "Music Theory", Music Appreciation, Art Appreciation, etc....
However, all is well and I understand you point that to some people "Music Theory" is a great learning opportunity.
