this is a question I've been sitting with some time, and I've come to the answer "no". but that's only me because 1-I don't have much of a social life 2-my alters take care of their situation so people in those situation see only the alter that takes care of a given situation. 3- there is an idea in my system that "nobody has to know".
my T recognises only the littles when they are "out". while my family just think "I'm just like that".
it seems to me that it's all just in our heads (but that's only my experience).
how do you experience it?
