I disagree... she knew it might be an issue. That’s why they didn’t ask permission. And, when told to leave the just did what they wanted. I’d kick em out of school and tell them they could finish in the summer.
If you’re going to pull the cheerleading squad off the field, you should at least have an adult reason to do so.
What these girls did was a harmless prank. It wasn’t offensive in the slightest, and it would take a pinhead to make a mountain out of this molehill.
If the school officials had a problem with it, they would have far ahead of the game to give the girls a few hours of detention the following week, and not make a fool of themselves at a public event.
The girls objected to being kicked out of the game. And if you were being kicked out of a game unfairly, I think you might have objected as well.
