Most people have friends, but aren't as close with them as they are with their best friends. There are several key differences that determine your best friends versus your regular friends.

1. Your best friend is not afraid to tell you if you look like a walking piece of garbage.

Obviously you want your bestie looking her best, and would never let her settle for less than that. A regular friend would always tell you that you look nice, out of politeness, when in reality, that yellow shirt does not compliment your skin tone at all.

2. Your best friend will always help you determine what pictures are Insta-worthy.

Again, you are always there to help your friend present herself in the best way possible. Even if you send her 23 pictures of the same selfie, she will determine which one has the best lighting. A regular friend on the other hand, would probably say something like, "Well, they all look nice, so it won't matter which one you post." Wrong.

3. You and your best friend aren't afraid to change in front of each other.

When getting ready for a night out, you know darn well that there will be hella outfit changes which are happening in the same room. A regular friend would be uncomfortable and probably go change in a bathroom, thus, slowing down the process.

4. You and your best friend know the tiniest details about each other's lives.

I am talking about knowing that her great-aunt Jane's 85th birthday is August 11th, or knowing exactly when your pal is due for her week-long monthly gift from Mother Nature. A regular friend is not as involved in your life, and she probably does not care as much.

5. You have probably seen all of the text exchanges between your best friend and her significant other.

And to be honest, you probably crafted half of her responses. A regular friend probably would not get as much exclusive information as you do on this topic.

6. You are probably too comfortable around each other that it kinda scares people off.

It is completely normal to send snapchats to each other on the toilet or with one of those ridiculously gross filter,s rather than looking halfway decent for an acquaintance. The worst is accidentally sending that ugly picture to a normal friend that was supposed to go to your best friend. Awkward!

7. No matter how sticky the situation, a best friend will never leave your side.

Through hell and back, your best friend is guaranteed to be by your side. You have each other's trust and will do anything and everything to help each other out in times of need. That's what best friends are for, right?
