Yes I know what you mean about defining them in physical terms. I draw some similarity to some people that want to get into photographs and don’t resist at all when asked. A bit like the relative in families that’s always ready with that special smile if you know what I mean. Others don’t want their photo taken at all and always shy away from the camera.
It’s the same with Orbs some jump into the shot and others won’t.
Just let them do their thing and see what happens I suppose.
I think they know we know of them though. Agree...?
