That's honestly the best kind of creative accident. Sometimes you just need something, or someone, to completely mess up your careful plans to see the problem in a new way. Getting too stuck in your own head can make every choice feel heavy and important. A random shake-up forces you to look at the pieces without all your own baggage attached. It's like your brain was focused on the wrong thing and the cat just hit the reset button. Those happy accidents are why I never totally dismiss a messed up draft right away.
