In an unprecedented bit of luck, it seems the head of fine arts for the district took my side.
My principal came up to me after school on Friday and said, "I talked with the head of fine arts, and we have a compromise. You can do this show for the contest, but you can't have a performance of it here on this campus." Which is totally fine with me, but it seems odd. How is that a compromise, and not a victory for me? The only scenario that makes sense is, the fine arts director told my principal that the show was not problematic (it was even done by other school in this district a while back), the principal didn't want to eat crow and tell me she had been overruled, so she had to craft some type of middle ground so it didn't look like she lost this one.
I've been butting heads with administrators for my whole career, and something finally worked out! I know this is going to be the year I finally get to see what I'm capable of.
