True story: when I was 10, I went along with my friend Maria to audition for a new selective children's choir in our town. It was a HUGE deal at the time and made the local papers (this choir went on to win lots of competitions subsequently!).
Anyway, we all turned up on our allocated day, and had to stand in rows,singing scales to the piano, whilst stern-looking women walked up and down the rows listening. If they tapped you on the head you had to sit down.
After about 15 minutes of this, around half the room were sat down...me included. My friend was still standing. The 'sitters' were sent home, unsuccessful, and the standers had passed and were in the choir. It was quite a brutal audition and very public. I actually still feel the humiliation of that rejection...not 'because' I was rejected, but because of how it was done. We were so very young and it was quite a harsh way to do it.
I was devastated because I'd always been told I had a great singing voice, and was a Musician in other areas too (piano/saxophone and flute). It really knocked my confidence.
Anyway...several years later, after working my socks off, I attended The Northern College of Music, did my degree, and sang for many years on the professional circuit (before giving it all up after having my kids and becoming a primary school teacher 🤷♀️🤣)
OP...the moral here is, never give up on your dreams! If you work hard and train hard, it can pay off. Hope your DC is ok ♥️
