1. You never leave each other without saying "I love you" or giving hugs.

Even though you know you'll see each other again, "I love you's" and hugs are a necessity.

2. You can tell when something is going on with one another even if you're in two different states.

Seriously, it has to be called like BFF telepathy. It is a real thing.

3. You walk into each other's houses with no knock or door bell.

You know you need to save energy for what you guys are about to do (sit on your phones together) so why get up?

4. Oh, what the heck! You don't even need to worry about the knocking part because you have their garage code!

This makes you feel very special because you know that only special people get the garage code.

5. You can ask each other to do anything for one another, no matter how gross it may be.

Gross? Like popping a pimple maybe? Not to your close best friend.

6. You know where each other are 24/7-365!

How's this possible? You share locations with each other and it is pretty amazing and not creepy at.

7. You have HUGE, adorable, not to mention MATCHING stuffed animals.

Not any stuffed animals... But bunny peeps.

8. You took things to a whole other level and got more matching things.

You each got a dog; brother and sister to each other.

9. There is absolutely no question about it, you're crazy when you're together.

You actually give crazy a whole new definition because of your two personalities.

10. You take the cutest pictures with each other.

You both are just so naturally beautiful and admire it within each other.

Finally, you the main thing you realize when your best friend and you are SUPER close is that you will be there for each other no matter what and always love each other through the ups and downs.
