I'm just worried that other studios are going to be full of the "pageant mom" types -- based on some of what I've seen at this convention, I think maybe my daughter is too nice to be a dancer. There seem to be a lot of 7-10 year old bratty divas out there!
I've learned not to judge my fellow dance moms in our studio. We don't do the fancy conventions but we did join a comp team. I was scared stiff to join, but the moms seem like nice regular moms after going for a few weeks.
My children are not bratty divas--but they can get attitude.
It takes a strong anchor in mom and dad to keep the kid level headed.
Just b/c your daughter is "too nice"--noone is too nice, too small, too big, too tall, too silly, too pretty, too ugly, too *insert any adjective* to dance.
Dance is for everyone.
It is unfortunate your daughter's coach is....an idiot.
I adore the French language. I am not good at it, but it is what I chose to study in high school. I was in my 3rd high school by senior year (military family) and got into a level III French Class. It seemed to go well in the beginning and I looked forward to a state competion called Congres (accent on the e, but I do not know how to type it--pronounced Kon-gray).
Our teacher--well, she spent my senior year working and completing her phD. I do not fault anyone who chooses to advance their education. It is a wonderful thing to do. But she did it at the expense of us. We did not know what we should have for level three and Congres was a joke. I felt like I was in a foreign country and hadn't one lick of french.
Our teacher was physically there but mentally absent. She was on some board or something--and there was some issues. The small team of us that went to this event felt quite abandoned thanks to that fruit loop. We all held her in contempt. How sucky is it to have a "A" grade in a level III french class but basically flunk on a competition competency test?
I did go on to take French in college (which was still of no use when I went with my Family to Paris in 2004. Hubby likes to joke on how NOT so well our first hour in Paris went on arrival when I could not communicate with the --not concierge, but something similar--of an apartment I had rented for our stay. All I was trying to do was say that we were waiting/meeting someone and not able to say it at all. I could ask for the potty though when dd had to go to the bathroom.

).
That being said, it is our teachers who set the bar for behavior in competition and in life. When they behave wrecklessly, it can really sour our attitudes on whatever it is we are trying to pursue.
I'd simply leave the studio and try another and you may never know. Since you had no comraderie--you were pretty much abandoned and left to fend for yourself at this competition. That would scare me as well.
But don't leave dance b/c your daughter is "too nice". It is precisely what they need in dance.
We can't let the art form get overrun by divas with attitude. Watch "So You Think You Can Dance" and you can tell the divas from the non-divas. It seems the divas, don't have much dance skills behind the attitude when it comes to picking the top 20.
Beware--DIVA crossing--and steer clear and avoid them. But not the art of dance!
