1. Netflix Nights.

"Bob's Burgers" just isn't the same without the Louise to your Tina.

2. Fast Food & Convenience Store Runs.

The amount of candy you bought makes you a little less insecure when you have your sister with you.

3. All her friends are like added little sisters who don't argue with you as much.

Even though your sister gets mad every time you talk to them or follow them on Instagram.

4. She'll be - maybe a little too - honest with you no matter what.

Your morning at home wouldn't be complete without the "You're really going out in that?"

5. You can complain about things your parents do together.

She has to stick through all the awkward family photos your parents put you through too.

6. You never have to worry that you lost something because it's probably just in her room.

Warning: she will get mad when you go and look for it and accuse her of taking it - even if she actually did take it.

7. She'll tell you how cute that guy you brought home actually is.

But she'll probably say they're all not cute just to make you mad.

8. You're confident your kids will have at least one cool aunt who lets them do whatever they want.

She'll give your kids way too much sugar and buy them a Barbie Jeep before she gives them back to you.

9. She'll listen to all your secrets.

Even if it's secretly and through your bedroom wall.

10. You have an entire second closet to choose from

However, she will try and convince you nothing of hers will fit you.
