Only those who have a deep connection with their sisters can understand the beautiful relationship of sisterhood. Sisters are the best - and sometimes the worst. You fight with them, laugh with them and watch each either grow up.

If your sister is your best friend, you'll definitely relate to these wonderful truths.

1. She's there for you in the good AND bad times

2. Even through your awful teenage years, you always knew you'd have at least one friend - your sister.

3. She's likely the only one who REALLY understands how to cheer you up

4. When everything else is crumbling around you, she's the one thing that stays constant

5. And no one knows how to tattle on you quite like a sister (even when it's her fault)

6. Walking down memory lane with her brings a wave of sentimental happiness

7. She encourages you because she knows what you are capable of. You believe her because she knows who you really are.

8. No one makes you laugh like a sister, especially during life's hard times

9. Even with your obnoxious habits, she loves you anyway

10. Most friends drift in and out of your life, but a sister is that she is there to stay.

11. She protects you better than anyone

12. And she knows how to hurt you more than anyone else as well (but she tries not to)

13. You're never more yourself than when you're with her

If any of these resonated with you, share them with your sister.
