1. You have multiple wardrobes.

"It must be nice to have a sister because you can share their clothes." While this is true, some people oversimplify this idea. In actuality, this is a much more complicated idea. Yeah sometimes it's all completely great and everything is on limits and life seems perfect because you have double the clothes, but sometimes sharing clothes is a battlefield that requires strategy. Like, she's going to be gone from 3–8? Perfect, I'll have 30 minutes to return this dress to her closet before she even knows it's gone. Or there's some kind of advanced level trade negotiation. The trick is never knowing if closets are fair game or off limits, you just have to feel out the vibe.

2. Having sister cliques

If you have multiple sisters, you're bound to have miniature sister cliques. These are temporary cliques when you have a stronger bond with one sister at a given time. Sometimes you're the odd one out, and that's OK; just try again in an hour or so.

3. You have understood jams.

Everyone probably has slightly different tastes in music, and there are always fights over control of the aux chord, but there are mutually understood songs that are to be played and sung at maximum volume. Has it really been a successful day if you didn't belt out "Since U Been Gone" with the sunroof open? Bonus points for attempting to harmonize.

4. The "your poor dad"

"You have three sisters? Your poor dad." You've heard this your whole life, especially from old people passing by at the grocery store. How are you supposed to respond to that? Should you say, "Haha yeah it's a real burden, wish I could trade one out for a boy or two." Little do they know that you and your poor dad bond over SportsCenter and grilling.

5. Having mutual opinions of people

When you have multiple sisters, all of their friends are also your friends. Likewise, if one of your sisters doesn't like someone, neither do you, and you better be there to listen to the vent sessions. Nod your head and agree with everything; use extreme caution when presenting opposing opinions.

6. You always have someone to hang out with.

Your friends can't hang out? Fine, you have a whole squad to back you up. No matter what, you can always find someone available to join you on your "just for fun" Target trips or early-morning coffee runs. And sometimes, you'd rather have a girls night out with your sisters anyway.

7. You never have to worry about forgetting anything.

Whether you're on a long trip or just out and about, you never have to worry about forgetting anything because odds are one of your sisters can back you up. Need snacks? Check. Hair brush? Yep. Blu-ray copy of "Harry Potter and the Half-Blood Prince?" You bet.

8. Always having a mediator

This is a big difference from just having one sister. When you have multiple sisters, you always have someone to be the mediator. When there are petty fights over clothing custody or ice cream rations, there's always someone there to put you back in your place real quick.

9. Being known as "the girls"

"Oh you're on of the *insert last name* girls!" Haha, yeah I'm one of those. When you have multiple sisters, you lose your first name and become all lumped together as one person. You also commonly are referred to as "___'s sister." Just smile and nod.

10. Always having someone to take pictures

When you have multiple sisters, you always have a photographer. Cute photo op? Just summon one of your siblings. They know that it better be a quality picture, or they'll be ostracized. On the other side, having multiple sisters means there are always Snapchats captured of your worst moments. So many unattractive screenshots, so little phone storage.

11. Having honorary sister members

There are some friends who basically live at your house and have become a part of your family, so you make them honorary sister members. The sisterhood's big enough for everyone.
