I've hit a little snag with one of my RPs and I was hoping that someone could give me some insight on how to handle this situation. 

What do you do when you've set up a scene for your partner and they completely ignore what you wrote? I'm talking about, no response to the dialogue, going off on their own and forgetting the limitations of the world with no regard to logic and no thought of the consequences within the story. 

Their post just doesn't make sense to me, and I don't know what to do with myself because I feel a little stuck. I don't want to ask them to rewrite it because that just seems rude, but at the same time, I have no idea how to give a quality reply.
