I was just remembering this, and this thread reminded me.

Several years ago I was in a little play at my synagogue. I had a lead role.

The cantor was the director. I have had a lot of performing arts experience. She had none. She was very haughty in her directing style. She was quite clueless in her choices. But I went along with it for fear of her wrath.

But, toward the end of the rehearsals, I couldn’t take it anymore. What she was doing was so wrong.

So, I started sending her private emails, ever so gently suggesting how the blocking is supposed to go. She would do what I said every following rehearsal, all the while acting like she was the grand director. I kept my mouth shut. After all, “The play’s the thing”.
