Reminds me of when I was a kid and began clarinet lessons (on my own initiative—my parents had nothing to do with it). The teacher set me to work playing scales, but I was impatient to play something that sounded like a tune. So I gave short shrift to the scales and skipped ahead in the book and practiced a tune instead. At my next lesson, I was too embarrassed to tell the teacher what I had done. (Or maybe she never gave me an opportunity to speak—my memory on this point is hazy.) She tested me on the scales and found me wanting, so she sent me to practice in a closet while she taught other kids. I was so humiliated I quit the lessons at the first opportunity. And nobody ever asked me why.
