So, I don't think I'm actually plural but...

When I'm feeling like "River" there is a noticeable change in my attitude, demeanor, voice, mannerisms, posture, confidence etc. compared with just day to day "me".

When I'm not in that mode, I think of River as "her" and think about what "she" would do or like. Like, I know what clothes and music and drinks she likes which isn't always the same as what "I" default to.

Plural/median system friends, does any of this resonate with your experience? And if so, how can I help River "front" more? Because I know she wants to...
