As much as I hate to admit it, my big sister might be sort-of, slightly, cooler than I am.

Sometimes. She's the one I call when I can't call mom and the only one in the family who can properly handle my attitude. Big sisters are the people you'd choose if they weren't already family, and here's why.

1. She is your first and truest friend.

Big sisters are (literally) there from day one. They see every dirty diaper, every bad haircut, and every melodramatic breakup. They deal with every bad day and drama queen attitude and still love you in the most unconditional way.

2. Her closet is your closet.

For some reason, her clothes always look better on you. Funny how that works, huh? With a big sister comes a big closet, and who doesn't love having a double wardrobe? I'd also like to take this opportunity to apologize for the clothes I will never give back (but I'm not really that sorry).

3. She knows what it's like to deal with your parents.

Anything you could possibly be going through, they went through it first. It's kind of like having an instruction manual or a key to the future. Either way, it's always nice to have someone who will always understand the struggle.

4. There are no boundaries.

Wanna dance around in your underwear all day? Cool. Life talks while she's on the toilet? Also cool. There's no awkward moments or changing in the bathroom with the door locked. There's just the kind of freedom that only comes with siblings.

5. Thanks to her, you know about all of the cool movies/music/fashion trends from years back.

Thanks to my sister, I have every Too $hort and Ludacris song you could ever think of downloaded on my phone. I've seen every cheesy '90s movie, and when a fad from 10 years ago comes back in, I already have the hookup.

6. She tells you like it is.

We all have those friends who tend to sugarcoat everything. Yeah, sisters don't do that. She's the first person to tell me when I'm making a terrible decision and that I really shouldn't triple text that boy again. She keeps it real with me and deals with my attitude, and that's why she's the best.

7. Her home is always open.

Sometimes you just need to get away from life and binge watch Netflix, and sometimes you need all of that plus your sister. She always has her door open when you're two seconds away from losing your mind, and she also has good takeout and a dog.

8. She knows what you're capable of.

My sister knows exactly who I am and what I can do. She knows when I'm not doing my best, and when I need to be set straight. She's always there to remind me who I am and what I'm capable of accomplishing. She's always been my biggest fan.

9. She's a lot cheaper than therapy.

For some reason, my sister always knows just what to say. Even if I don't see it at the time, she's usually right (don't tell her I said that). Big sisters are like wizards, somehow they always magically make you feel like life's gonna turn out alright in the end. If she wasn't already awesome at everything else, I'd suggest she be a therapist.

10. She will always be your go-to gal.

No matter the situation, she will always be by your side. There is nothing you could say or do to make a big sister leave, and that's why they're the best. Whether it's a speeding ticket, a mean girl or you just need to laugh, big sisters are always going to be there to lift your spirits and set you straight.

I couldn't make it without ya sis, I'm sorry for ratting you out on Thanksgiving that one time, and for running away at the zoo. Thanks for taking me to see Aaron Carter even though he's way too old to still be singing "I want Candy," and thank you always for being the best role model, sister and friend I could ask for.
