Does anyone IRL know you are plural?
This one is real simple lol.
Our family who are dead to us know but likely don't believe it.
A couple mental health doctors of various kinds know.
Our ex-best friend knows, though if we could erase her memory of every inner circle detail we shared with her we would.
A few of our roommates through the years have learned, no current members of the household know though.
The head of our film course in university knows cos it felt relevant to potential deadline extensions since "I forgot cos I personally didn't hear about it" holds more weight than "I forgot" on it's own, he's cool about it.
Someone on the student union finance team knows, he tried to see if he could use it to help improve our funding for us but that was a dead end, really great guy, sometimes we see him around town, he's got wild fashion tastes so it's impossible to miss him lol
No one we currently have regular in person contact with knows.
