The voices are TOUCHY do you understand me?
Touch-starved extremely tactile shameless and needy for any and all type of contact. Yes, even the most reserved or weary ones.
None of them had bodies, they just where a part of something connected and if they are to be on their own the thing that could replace that is physical contact.
In the same vein, they don't have a recognition for personal space that hasn't been cut in some way by the others. But even if they do ask for it or respect it in some cases, they will always find themselves in any of the other's space like a gravity pull.
Hugs, hand-holding, cuddles, piling on eachother, grabs, punches, maneuvering around one another, pulling, bitting, fighting, preening.
You name it, that's how they act.
