I have more sides than a d20.
There's the side I show the professional world, the sociopathic, money-grubbing, complete monster side of me. I hate that guy. He's a douchebag. But it's what employers and business people want.
There's the side I show the girl in my life, the supportive, warm, friendly side that I think is probably closest to my "true nature"---which is good, because she deserves better than some guy trying to play her. I can say without a trace of sarcasm, irony, or deception that what she gets is 100% sincere. I love that person---the me I become when I'm around her.
There's the side I show my male friends, the sports fan, meat-eating, "how's the wife and kids" man's man beer commercial side. This is the side of me that gets the "You're alright, bud" compliments.
There's my creative side, deeply personal, rarely shown to the world unless I have a finished product to show. When I'm writing, I withdraw very deeply into myself, which brings me to...
My autistic side, which I try to rein in for my own good. I was diagnosed "atypical autistic" in my teens and I have learned to grant that element of myself plenty of leeway lest it destroy me. This is the side that goes hand-in-hand with a lot of my intellect and skills, both useful (accounting, finance, writing) and useless (playing video games, holding a bunch of sports stats in my head to use in conversation.)
And dozens of other sub-"sides" that seem to pop in and out.
