I am a little confused about what you're asking, so I will answer both ways

we know someone who we talk to via email with DID, she has alters of various ages- and sometimes they do interact with us (so for example, alicia from our system might talk to cathy from their's) about something age appropriate

in real life, we don't really have many friends at all. when people do start working out we may be DID, it's hard- and we try and hide it from people. stacy has a few friends, and they don't know

our host emily, actually did get found out once

because this guy adam (an outsider), was talking to 1 of us about the greek gods, and she goes.. I like atlantis and stuff, but none of it's real

and adam shoots back with: yeah, michelle isn't real, either and launched in to a conversation about what he thought was going on.

very... um, well, surprised by the whole thing- we don't actually talk now as he thinks it's weird having multiple people
