I think it’s both. And it’s okay to feel envious.
Most, if not many, Dopers know I have a twin who’s also a Doper. Growing up, she was always the pretty one. Despite the fact that for most of our lives, we looked damn-near identical. Like, we could play the whole switch-a-roo thing in school and the teachers wouldn’t know. Yet she was the pretty one! I think it was all in the smile. I couldn’t do it “right”, while she was a natural. She was also the smart one because she was more confident and well-spoken. While I was the goofy, crazy, “retarded” one. Totally irrational (well, maybe not the “goofy” or the “crazy”…let’s be honest here); I made better grades than she did, and tended to do better on standardized tests. But noooo! I was not only the ugly one but I was the dumb one too! And people would mistake me for being a year younger than she was because I was shorter. Talk about giving me a complex!
I hated always being the bad one in all possible dichotomies. I didn’t care about looks, and I knew I was smart (or at least, just as smart), but it didn’t matter. Until we went our separate ways, we were going to be compared and that was that. Life sucked back then.
And then we did go our separate ways, both of us leaving our home town. She developed her own personality and interests, and so did I. As we matured, people began to see us as individuals, with our own merits. Instead of being the crazy retard, people (who’d never met my sister) acknowledged me for my good humor and quirkiness and off-the-wall intelligence (like, I betcha don’t know what the state tree of Colorado is! Ha! I totally pwn you!!) And as I’ve gotten older, I’ve cultivated my own sense of style and beauty. Now when I go home to family, they can see it too. My outfits and hairdos get tons of praise, whereas before I might as well have been invisible.
Meanwhile people started seeing my sister for more than just the “fluff” stuff. For instance, she’s a great performer. She was the lead actress and director in all the plays that her vet school put together (yeah, I don’t get why vet students would be putting on plays either. They should be studying about dogs and cats, not doing bootleg versions of “The Wiz”). Folks at home started appreciating her hard work and ambition, as well as her good looks and intelligence.
In other words, we both became three-dimensional. She’s no longer the “good” twin, and I’m no longer the “bad” twin. We’re just individuals. Yeah, we both hate that there’s still a two-inch height difference between us (she feels like an Amazon and I feel like a dwarf next to her) and like children, we play battle of the doctorates (a Ph.D is far superior to a DVM, because I am a DOCTOR OF PHILOSOPHY!!!) But we now recognize that we’re both beautiful and intelligent and likeable, in equal measure. Fuck everyone who doesn’t agree!
I say give it time. When you hit your late 20s, early 30s, your sister won’t be as hawt anymore and you’ll probably get more head-turns too, while your intelligence will become even more impressive as you take on the world. And to your sister’s credit, she’ll probably garner attention in another, less superficial way. It will all even out in the end. Maybe not tangibly (my sister and I aren’t tangibly equal), but it will feel that way.
