That makes sense. The emotional imprint seems to be "That's mine/private!" or "It's not ready!"

And especially performance art, like dance* - well, it often isn't finished until rehearsal is done and you've worked out the problems, and you're using the show outfits/lighting/costumes. Plus, a lot of people might be self-conscious at earlier stages.


*I am not a dancer, and I usually don't like being stared at.
