I may be one of the few people on the site who completely understands ghosting and is more or less ok with it.

My pet peeve is when people are all precious about control of their character. Look, I get that you are attached to your special little guy or whatever but I am in no way going to stop writing a scene because I need some minor action from them. If it seems in character I'm just going to write it and move on. I don't mean some huge thing, I won't make your character kill anyone but if I just need a nod or a few words I don't see any reason to stop writing. Worse, if I do stop, it often leaves a scene at a point where there isn't that much for you to logically do other than whatever small action it is I require and I hate it when people do that to me. Of course it goes without saying that all of this is reciprocal, although tbh I'm much more permissive with my own characters. If we are going to write a story together, we might as well write it TOGETHER.
