Everyone has that best friend that they’ve done absolutely everything with. You’ve grown up with them experiencing life and all of it’s ups and downs, and somewhere, along the way, you found that you had become part of their family, and they’ve become a part of yours. You don’t know when or how it happened, but being a part of your best friend’s family became as second nature as being a part of your own. At this point, you might as well be related.

1. Their parents treat you like one of their own.

They’ve comforted you when you’re sad, praised you for your accomplishments, and always make sure to give you the best advice; they’re basically your second pair of parents.

2. This means that they expect you to help out around the house.

You’ve washed their dishes, made their beds, and helped with the groceries. Sometimes you do more chores at their house than your own.

3. You have inside jokes with their parents.

You’ve spent so much time with your best friend’s parents that you have loads of inside jokes, some of which your best friend doesn’t even know about.

4. You hang out with their family, even when they’re not around.

Who cares if your best friend already had plans? You'll just make plans with their little brother anyway.

5. Their siblings are basically your siblings.

Odds are you probably spend more time with their siblings than your own.

6. This means that you argue and get annoyed with your best friend’s siblings just as easily as you do with your own siblings.

There have been plenty of moments where you’ve lashed out at their siblings and they have lashed out at you too, but it never seems to make anything weird between you because you’re basically related anyway.

7. No family vacation is complete unless you’re invited to go along.

You’ve gone on nearly every family road trip or vacation, and when you’re not invited, you get pretty offended; how dare your family go on vacation without you?

8. You get invited to every family function.

You’re in attendance for every birthday, wedding, and celebration, and if you’re not there it just does not seem right.

9. You even make appearances on holidays

You can’t celebrate the holidays without your family by your side, so you’ve definitely made an appearance for some Thanksgiving pie.

10. You’re together so much that their distant relatives have definitely wondered if you’re actually dating.

If you and your best friend haven’t been mistaken as a couple, you’re probably doing something wrong.

11. You’re up to date on all the family drama.

All of the relatives clue you in on the latest family gossip, and it fills you with pure joy getting to be in the loop.

12. And sometimes you have front row seats to watch the drama unfold.

Nothing is better than seeing the family drama unfold before your eyes like an episode of "Real Housewives" and then getting to gossip about it later.

13. You’re regularly mistaken as part of the family when you’re in public with them.

Strangers have referred to various members of your best friend’s family as your own, and you just go along with it because they’re basically right anyway.

14. You basically live at their house.

You're there enough, you might as just well move in!

15. You regularly show up unannounced or uninvited.

Who needs an invitation when you’re basically a part of the family?

16. Knocking before entering their house is such a foreign concept.

At this point in your relationship, they’d probably find it strange if you knocked on their door.

17. You’ve even hung out at their house when no one was there.

Show up and no one’s home? Might as well just kick back and chill with their dog and eat their food.

18. What’s yours is theirs.

You eat all their food, sleep on their couch, and most importantly use their Netflix account.
