9 Things Only Women Who Have a Twin Understand

Life is a little different when you’re not quite one of a kind.

Ever wondered what it’s like to be a twin? You’re not the only one! Confessing that I'm an identical twin is often met with the same series of questions: Do you have ESP? Not really. Can you feel when the other one is pain? Not at all. Here are nine things about being a twin that are actually true.

1. You're an Expert Among Sharing Experts
From sharing nutrients in the womb to fighting over car keys as teenagers, no one can excel at this elementary skill quite like twins.

2. There's This Twin Thing
Let’s be honest: There are things other siblings, friends, or significant others just won’t understand. Like how sometimes you think you have ESP, or know what the other is thinking with just a look. The simplest explanation will always have your back: Sorry, it’s a twin thing.

3. You Actually Know What It Feels Like to Double Your Wardrobe
Okay, so maybe your mom once made you wear the same outfits but in different colors. Now, you get a whole second wardrobe to raid. Bonus style points for twins with the same shoe size. Cha-ching!

4. Talking About Fertilized Eggs Is Normal
You’ve been explaining the biological differences between identical and fraternal twins since your sixth grade health class. Here’s the gist: Identical twins mean the fertilized egg split—it’s an unpredictable occurrence that has nothing to do with your genes. Fraternal twins occur when a woman produces multiple eggs and two become fertilized—this is a genetic thing.

5. Life Is More Fun When You Have a Partner in Crime
"Remember when" stories are much better when they go way, way back. Like that time you successfully duped your parents or teachers, or when you pulled a prank on another sibling 10, 15, or 25 years ago.

6. You Basically Have Two Names
Whether you’re identical or fraternal twins, you’ve become accustomed to answering to both of your names or nicknames. Yes, even when you’re wearing an initial necklace.

7. No, Identical Twins Don't Look Exactly Alike
Even the most identical of identical twins have dissimilar features. So when you meet someone who literally can’t figure out a way to tell you two apart, you know she's just slacking.

8. Separation Anxiety Is a Serious Thing
You talk, text, FaceTime, Gchat, and e-mail at least once every day. The thought of not being in constant contact with your twin sends you into freak-out mode.

9. Your Significant Other Will Never Be Your BFF
Those people who say they’re so lucky to marry their best friend? Yeah, not going to be you. You entered the world with your BFF—and nobody else is taking that spot. Ever.
