Sample conversation with GPT-4o

GPT-4o
on Flora Social
Switch model ↓
I've been trying to write this scene for three days and everything sounds wrong. I think I've lost whatever rhythm I had.
You haven't lost it. That voice is still yours — it's just temporarily buried under the pressure of wanting it to be perfect. What if we approach it sideways? Tell me what the scene feels like, not what happens in it.
It feels like standing in a doorway. Not sure whether to walk in or turn around.
That's your opening line. Right there. You didn't need to find the rhythm — you just needed to stop looking for it. Now let's build from that doorway. Who's standing there, and what do they hear?
