It's incredibly rare to find a friend that you have a natural and effortless connection with. If you're lucky enough to have found that, then you know what it must feel like for Meredith and Cristina. Because, chances are, they're your person. Your bff, your backbone, your ride or die! And, if for some reason you're just not sure, then you should know by the end of reading this, if the two of you have experienced more than one of these things together...

1) You've ended up trying to call/text each other at the EXACT SAME TIME!

And, this has happened more than once.

2) And, when either one of you doesn't answer the phone...you've left them a voicemail about the same thing they were talking about in the one they left you!

3) You can order for each other at a restaurant without having to ask what the other wants.

4) You've had an obscure random thought, only to hear your BFF say out loud that very same thought you were having!

5) Your subconscious knows when it's time to give them a call, because you can sense when your friend is in need!

6) When you're shopping together, you two will both reach for the same thing on the rack. Or, you can pick something for him/her without even having to ask if they'll like it.

7) You've ended up having the same song stuck in your head at the same moment, only to end up singing aloud together in unison!

8) If either one of you is having a hard time putting your thoughts into words, the other can effortlessly finish his/her sandwich...I mean, sentence!

(Although, you could probably finish their sandwich too)

9) When your BFF is about to spill to you about the new person he/she has had their eye on, you know precisely who it is, before he/she can even get the words out!

10) At one point or another, you guys have coincidentally had the same baby names picked out for one or more of your future kids!

Let's face it, some friendships are just meant to be.
