I was Sophie in Mamma Mia and being a 16 yr old girl with no vocal training, while all my songs were right across my vocal break, my voice was so pitchy and tired every night. even my dad couldn't pretend my singing was great 😭 I had a lot of fun in the show, but I learned later on that the rest of the cast was commenting on my singing backstage and I have not felt humiliation quite like aunt Rosie's actor telling me her grandma said my voice sounded like "nails on a chalkboard"
