How do I know who I'm talking to?

My system has spent 25 years, more or less, hiding itself. Fundamentally, it exists in order to survive, which has meant cutting out and hiding pieces of awareness that were unbearable, and hiding secrets from the world. And (I say with almost Shandra level pride) it's overall pretty good at it. Even in the most safe places with the people I trust most it's almost impossible to get over the fear. So I'm not sure that the system would want the mysterious "you" to know who you're dealing with, exactly.

I have no idea what cues we give off in terms of body language, because when I'm in the body enough to be aware of them, they're consistently how I move the body around.

So I guess I'll have to guess from the way other people handle me and the system. Most of the time, whoever you think is "me" will be "me" because whoever talks to you is the one who talks to you. For the rare people who get to speak to more of the system... hmm. In person, Carl is often able to guess, but he will ask from time to time. So far people are generally not comfortable announcing 'now you're talking to me!' but they do have their ways of getting it across. My therapist asks for an introduction, but we are not always so obliging.

Online, we have tried the experiment of (usually) being separate, although we occasionally do jump into each other's personas, often by reflex or accident. During these jumps I've noticed people noticing and asking who they're talking to.
