Siblings can be the absolute worst sometimes. They tattle on you. They use your stuff without asking. They tease you mercilessly. Sometimes they gang up on you. Your parents yell at you when you didn't even start anything.

Okay. Put that all aside. Think for a moment. Would you still be the person you are today without them? Probably not.

Here are 10 reasons why siblings are the greatest gift your parents gave you.

1. They give the best advice.

2. The only ones who can tease you is them; anyone else is going down.

3. When it comes to having fun without your parents around, siblings (especially older ones) know what to do.

4. Siblings can understand when you think your parents aren't being fair.

Prime bonding experience.

5. Yes, they are the ones who know how to pull off being fake sick to stay home from school.

They won't help you without a price, though.

6. Real talk when you need it.

It's called tough love.

7. They teach all kinds of things about life.

Like the importance of sharing.

8. They know what to do to cheer you up.

Especially if they caused it and they don't want to be yelled at by your parents.

9. They understand all the weird things you do and still think you are a dork.

This is prime teasing ammo.

10. Despite all the teasing and fighting, they are the ones who will be there for you not matter what.
