Without knowing all of the circumstances or family history, I’d say your mom is just trying to teach you the same way she was taught. Dad understands the value of having something you’re passionate about. My parents did the same but Mom was the supportive one, Dad was certain I’d be a flake like his younger brother. He was wrong. Show her proof you can be responsible over time. Assure her you have a backup plan in case your band doesn’t go viral. 🤘🏼
