We all have that person that we could never live without. They make the world – your world – a better place. These are 25 things to describe your relationship with your best friend.

1. When you are in the car together, it is a necessity that you sing at the top of your lungs to classic Disney throwbacks, even though neither of you can actually hit any of the notes.

2. You are basically sisters, so her parents are your parents, and your parents are her parents.

3. Your clothes are their clothes and their clothes are your clothes.

4. You stay up all night, drinking hot chocolate and talking about your life. It isn't until one of you falls asleep that you call it a night.

5. You count on them to be your own, personal life coach and motivator. They always seem to know how to boost you up.

6. They are the first person you call when you feel like everything is falling apart. And, no matter what is wrong, they find a way to make you laugh.

7. You both have an unhealthy coffee addiction… and you know exactly what to order for one another on any given day.

8. You have those weird inside jokes that no one else will ever understand.

9. You never let each other forget those stupid, embarrassing, things you do, and you're always sure to keep photo evidence to relive the moments.

10. They refuse to let you be anti-social

And drag you out of bed no matter what you say. And, even though you were reluctant to leave the house at first, you always end up having a great night.

11. You tell them all those gross and uncomfortable things that no one else would want to hear.

12. You spend so much time together that people sometimes get you confused.

13. You always sleep in the same bed and, somehow, you always wake up cuddling... and it’s not weird at all.

14. When one of you gets a significant other, you make it clear to them that dating one of you is basically dating both of you. And your best friend makes it clear to them that, if they hurt you, she will make them regret it.

15. They’ve seen you at your absolute worst… and they take pictures so that you can never forget it. But, when the time comes, they know how to help you look your best, and they make sure you know how beautiful you truly are.

16. You have the same sense of humor and can match one another’s sarcasm.

17. You know everything about each other… and can even finish each other’s sandwiches. Wait, I mean sentences. (But, sandwiches too... no food ever goes uneaten when you're both around.)

18. You have that thing that you do together whenever you need to take your minds off of life.

19. You consult each other before doing anything, no matter how major.

20. They know when you need to just drive to Taco Bell at 3 a.m. for a cheese quesadilla… and then to McDonalds for a large fry… and then to Dairy Queen for Blizzards.

21. Even when they don’t make sense, they make sense.

22. You can complain to them about anything and they will completely understand.

23.They can see right through your bull shit and won't let you get away with it.

24. Nothing can separate you. Not even distance. You both know exactly how to pick up where you left off.

25. Best of all, they are your favorite person on the entire planet. They are the person you know you can’t live without. The one you want next to you in hard times, and celebrating with you in good times. It is their shoulder you want to cry on when things go downhill. You take them everywhere because a memory isn’t complete unless they are a part of it. They understand you better than anyone else. They are your person, and you believe wholeheartedly that they were put on earth specifically to keep you sane.

Here’s to best friends. Hold them close, thank them for existing, and never let them go. They are rare, they are special, and they make the world a more livable place.
