Just tell Mom and Dad that you can't make up your mind between being a teacher or a musican and that you would like their advice, I'm sure they'll do whatever they can to help you get that teaching degree. Your parents want the best for you, but your education is an investment in your future, and it should prepare you for something you can see yourself doing, hopefully something you have a passion to do, and if teaching doesn't work out for you, you can still become a big superstar musican like Sting, I still want to be a cowboy when I grow up...............
