We are also a secretive system, the ones of us that switch in and out daily life are (mostly) coconscious without time loss these days, so if we talk with every day people about something another one of this group has experienced we talk about it as "I" or "me". We don't talk about the alter in the third person when we are talking with people who don't know about our DID. We are even secretive about which one of is out and talking with our therapist. Only one of us has shared her name with our therapist and now our therapist will use her name in conversation when she recognizes that is who she is talking with, but other than that none of us are comfortable telling her. Sometimes the one who uses her own name will tell the therapist that so-and-so was out earlier if she knows about it.
Convoluted I know... basically 99% of the time we talk about things alters have said or done as "I" did or said that. Even though sometimes (if it is another person telling us something another alter must have done or said) we have no idea what the heck they are talking about because we have no memory of it whatsoever!
