Oh, geez. I write mostly from character or relationships, but there have been instances when I wrote from plot/idea. In fact, I think in a way, that caused some miscommunication with a beta reader on one story, in kind of the reverse of what you're talking about. I was exploring an idea, and she wanted the character element, and when she'd ask me what I was trying to do, I'd kind of blink and say, "Really, I think I'm just trying to tell this story." But I can understand the confusion, because I almost never have plot as a focus. Half the time, I don't even have one.
