Y'know what the weirdest thing about having multiple identical inner voices is? Weirder than the fact that I don't know if I'm plural due to the lack of practically any discerning differences?
The WEIRDEST thing is I don't ACTUALLY know how many fellow voices are in my noggin because they really ARE effectively identical. Could be as few as 2 (though I would suspect at least 3) or as many as.... well, some near infinite very huge large number XD
