"Sadly" just doesn't do this indignity justice. The fact that the administration actually participated in such a farce just makes my blood boil.
I've seen too much "plausible deniability" in my life not to recognize it when it happens, and this is a classic case. "Oh, we had no idea there was another dance - and no, we weren't suspicious at all when we only sold 7 tickets..."
There needs to be some kind of punishment for the perpetrators of this indignity - both the administrators and the parents who sponsored the alternative dance. I'm not talking about jail or getting them fired, but something - anything - a pay cut, a demotion, or better yet, public humiliation!
Unfortunately, the public stocks have been outlawed... but it would be perfect.
