I guess I thought it might be considered rude, and while my piano experience doesn't revolve around my teacher's happiness, our relatively good relationship is important to me and I wanted to make sure this isn't some kind of weird piano faux pas. There's quite a lot of foreign culture in classical music instruction that I'm not very familiar with. I've always found my teacher to be very agreeable, but apparently that's not that the opinion of some of his other students. I'm probably the least advanced of his students, but some of them appear to be on his "bad side" so to speak, and they've told me tales a good deal more severe than any interaction I've had, even during my early lessons where I was a nervous wreck the entire time and literally struggled to play scales. So with that in mind, I see that it's in my best interest to keep our relationship on good terms. Especially given that as a student in college, my options for study are limited to the two department teachers, and the other teacher would probably sooner attempt to teach Chopin to a chimpanzee than a student with my limited background
