She is the person you couldn’t stand when you were a kid. The person you fought the most.

But at the same time, she has always been your second half, your person and your partner in crime. She is your sister and this is why she is the best friend you’ll ever have.

1. No one knows you better

Let’s face it—no one could ever know you the way your sister does because she is one of the rare people who knows literally everything about you.

This is the girl who has the ability to read your mind. When you were younger, the fact that you could never hide anything from her pissed you off but now you know it is a true blessing. After all, who wouldn’t like to have a person who knows something is wrong even if we don’t say a word?

2. She has seen you at your worst

When you are talking about the qualities you would like your BFF to have, one of the most important ones is that she sticks by your side through thick and thin.

And this is exactly what your sister has been doing ever since you can remember. This girl has seen you at your physical and emotional worst and she still loves you the same, no matter what.

3. She is always honest

We all have a tendency to be annoyed by the ‘mean’ friends who tell us the ugly and harsh truth right to our face. But as you grow older, you realize that this is the type of people you need around. And your sister is the most honest friend you’ll ever have.

She is someone who will always defend you in front of others but will have no trouble telling you everything you need to hear when the two of you are alone, even if you don’t like it.

4. The two of you share incredible memories

Actually, the two of you share all of your memories. You never run out of things to talk about and what is even more important—you never have to explain yourself to her because she knows why you’ve become the person you are today.

5. You can talk to her about family matters

No matter how close you are with your friends, there always exist some delicate family matters that you don’t feel comfortable sharing with them. Well, there aren’t any forbidden topics with your sister. She is the only one who will understand you regarding all of your family issues, because she is fighting them too.

Reasons Why Your Sister Is The Best Friend You’ll Ever Have

6. She is always there for you

It’s never too late to call your sister just because you need someone to hear you out or simply because you can’t sleep and want to chat. She’ll never be too busy or too tired for you.

This is especially great if she is just one room away from you.

7. You two have a lot in common

You and your sister are two different people. But even if you don’t want to admit it, the truth is that the two of you are much alike. The truth is that you share many common physical features and personality traits, despite all of your differences.

And who could understand you better than someone who is the spitting image of you?

8. You are never ashamed to tell her your deepest secrets

We all like to avoid embarrassing situations and there are some deep secrets that you are ashamed to share even with your best friend.

But everything is different when it comes to your sister. You know that she is the only one who will never judge you or use your vulnerabilities or insecurities against you.

9. The two of you can never fight for real

When you were a kid, you fought with your sister all the time. If she is younger than you, she annoyed you. If she is older, you were jealous of her.

But all of this changed as the two of you grew up. Now you know that you can never fight with her for real. Even when you disagree or argue, you know you’ll bounce back to each other in no time.

10. She has to put up with you

Finally, your sister simply has to put up with you, whether she likes it or not. You are her blood and she doesn’t have any other option than to keep you in her life.

She is the person who really gives forever in BFF a true meaning.
