I’m sorry that you find it offensive that your child is not center stage. I’m sorry that you believe that you should no longer “encourage [your] child to do things [from which] she will be rejected”. Personally, I am no stranger to rejection, yet my parents have supported me in almost all of my endeavors despite the likelihood that I will fail and watch others succeed. However, learning to lose, they taught me, is far more important than learning to win. I can’t tell you how many times I have auditioned for roles or opportunities that I didn’t receive. I can’t count the number of performances that haven’t gone well or that have earned me negative feedback. Those experiences, however, can build you up instead of tear you down if you handle them maturely. As for favouritism: I have been rejected by close friends and even my only sibling on MULTIPLE occasions for shows that I was really excited for. I understood, I didn’t hold it against them, and in the end, their decisions were best for the overall quality of the performance. If you think that any current student director would stoop so low as to base our casting decisions on friendships, you don’t realize how many people you are insulting. Actors earn their roles not by having their parents bully the directors, not by being friends with the right people, but simply by way of hard work, talent, and perseverance. You can start with perseverance: accept the fact that rejection is part of life and doesn’t need to stop you from trying again and again and again.
Besides, your children are perfectly capable of making their own decisions at this age. They don’t need to give up just because the real world offends you.
P.S.: If you actually want anyone to take your complaints seriously, you might want to try forming grammatically correct sentences or even using spellcheck every once in a while.
Thanks for your time.
