When someone tries to control the character that I'm playing.

You can say what my character is doing directly, and I won't answer. Like, let me chose what my character does, or else you don't need me in this roleplay. You only need yourself to roleplay with if you're going to control me.

Now, you can drop little hints about what you want my character to do, ad there's stood chance that I'll do it. But if you flat-out tell my what to do, no. Just no. Do not expect an answer from me if you do that. Go ahead and stop right there with that mess.
