I’ve had the opposite happen. I (unknowingly, at the time) rejected a girl whose friends told me she liked me by going “haha okay then” and walking off, assuming it was a joke. Only realised nobody was laughing and it probably wasn’t a joke ten years later when the memory popped back into my head.

She seemed pretty happy dating another guy when I last saw her. Good for her, hope I didn’t hurt her too much by dismissing her like that. Would’ve absolutely crushed me had I been in her position.
