You too are missing the point. It basically boils down to this:
PAY ATTENTION.
On an open, public forum, we--as rp'ers--shouldn't HAVE to ask permission or set up stuff in the OOC for public interactions. You saying that YOU have no control over YOUR OWN interaction is not true at all.
OOC should NEVER interfere or determine IC interactions. Even plot wise, we should have a general idea and trust our fellow rp'ers to become their characters and interact in believable ways. As I've said before:
You want exclusive interactions? Do it in a PM and post it as a collab post (I.e. Hikari showing Haurka his familial grounds). Don't get mad at me because my character happened upon yours, initiated interaction, was ignored, then brushed aside then I called you both out on it.
If you were tired, all you needed to do was say in OOC: "Hey, it's late. I need to go to bed." Not bs your way out of interaction. If my character is locked, then she is locked.
