At least she didn't try to make you play the tuba.
As I got independent guitar lessons in junior high and high school, various people encouraged me to try out for jazz band at our high school so I could play guitar with them. I declined because I was too worried that playing guitar would seem more like "work" and less like "fun." My independent instructor was teaching me Sabbath, Metallica, Hendrix, Zeppelin, AC/DC, teaching me scales that I applied to writing my own shit.... What was jazz band gonna teach me that I might actually have fun with, you know? Although the other rock/metal guitar kids in jazz band liked it, but... I dunno... I didn't want to risk guitar becoming an obligation rather than something I loved to do.
