I am reminded of when my sons voice was changing....for a whille, I thought he was trying to learn how to yodel! ;-)
I remember one young man in particular. We were having parent/teacher conference. The young man had been adopted when his parents were older and he had impeccable manners I was one of the last teachers she met with. She broke into tears-— her well mannered son had gotten repeated conduct comments from the other teachers — class clown syndrome
He was just becoming the “normal obnoxious” that comes with the voice change Once we all talked about what was happening, he turned the corner and was fine. No more acting out. His beautiful FULL bass voice soon sang in the church choir.
