1.
You passionately hate people solely because your sister hates them.
2.
You tell each other the honest (probably harsh) truth about any questionable clothing purchases.
3.
You will break up with someone the moment you realize your sister doesn't like them.
4.
You tell each other the good, bad, and very ugly intimate details of your romantic relationships.
5.
And as a result, you'll be rude to their significant other when you know they're in a fight.
6.
You call them when you're scared shitless and walking into a dark or empty house.
7.
And you have no shame staying on the phone with them while you're in the bathroom.
8.
You steal each other's clothes without an ounce of remorse.
9.
And you get incredibly pissed when they do the same thing to you.
10.
You have ugly pictures ready to send each other at a moment's notice.
11.
And you keep ugly pictures of them as blackmail – or just a reminder for them to stay humble.
12.
You text each other pictures of complete strangers who you think they would find attractive.
13.
You share inside jokes about your parents.
14.
You speculate on which of your parents' friends are attractive.
15.
When you have bad news, you tell them first... so you can practice before telling your parents.
16.
And whenever possible, you and your sis try to tell your parents all your bad news at the same time, to lessen the blow for you both.
17.
You send each other pictures of any weird rashes or suspicious moles you might have.
18.
You back them up in any fight with your parents, even if they are completely wrong.
19.
And you get super pissed when they don't back you up, even if you were completely wrong.
20.
The slap-fighting you did with each other as kids? Yeah, you still do that, as grown-ass women.
21.
They are the only person in the world you can have a blowout fight with one minute and then completely forgive the next.
Because at the end of the day you'll always be best friends.
