Meredith and Cristina were each others "person." Here are 10 ways that I knew I found mine.

1.Going out isn't as fun without them.

You always make plans with them, and going out without them doesn't feel the same.

2. You have some of the best talks with them.

There are just some things you can only talk to some people about. They are one of those people.

3. They remind you how important you are even when you aren't feeling like you are.

Sometimes you need a little bit of reassurance, and they are always there to give it to you.

4. They call you out when you need to be called out on things, and you can't even be mad about it.

You guys do things that bug one another, but you aren't afraid to call each other out on it. The best part? Neither of you are ever even mad that the other one does.

5. You come as a package deal.

You are seen everywhere together. Being away from each other even one day feels wrong.

6. They believe in you, and believe you can do anything you set your mind to.

Sometimes you just need to hear those four words, "I believe in you." Hearing those words from them especially means a lot.

7. You can be crazy with each other no matter where you are.

From random dance parties to singing at the top your lungs in the car, it doesn't matter where you guys are, you will always act crazy together and have fun while doing it.

8. They don't let you do anything stupid, alone.

You get crazy idea that always pop into your head. You're afraid that you will have to make them happen alone, but not true at all. Your "person" is always right there beside you from the very start.

9. They're the first person you will run to when you are feeling sad.

We all need that one person who knows exactly what to say when we are feeling sad.

10. You know that you will always be friends.

People come and go. Things change as years go by, but even through the years that go by and the people that go, you know that your "person" will always be your person.
