One minute you guys are best friends, the next you're up in arms. At the end of the day, you're forever friends and thick as thieves. Overprotective and ready to lay down your life for them: Can't live with 'em, can't live without 'em.

1. Car rides.

"Nope, that's MY seat, know your place."

2. Santa buys you the same clothes for Christmas.

Twinning.

3. Sometimes fights would get physical.

Hair is pulled and people get bitten.

4. Always begging to hang out.

On the rare occasion, they would say yes.

5. Sabotaging them and pretending it's an accident.

I swear Mom, I have no idea why they're crying.

6. Stealing their clothes.

*Hears footsteps- runs away half naked.*

7. Getting caught going through their things.

It's not what it looks like...

8. When someone tells you how much you look alike.

Really, I don't see it.

9. Always having someone to talk to about life problems.

Because they've made plenty of mistakes... actually care... and therapy is expensive.

10. Sneaking you drinks at family functions.

Or pretty much whenever you ask.

11. At the end of the day, you always have each other's backs.
