1. If you and your best friend were lucky, chances are you were not even on each other's radar when you first met. More likely, things started off a bit rocky.

Until you realized that this person really was not so bad.

And was maybe even a little bit quirky, just like you.

2. You started to do the basic things together, making sure you were always the better half.

3. There came a point when you became each other's go to for going out, whatever fantastic and embarrassing videos may have come of it.

4. Eventually you realized that maybe this crazy cat is actually your better half.

5. To your disbelief, you started to think about other people besides yourself.

6. In spite of your best efforts, there comes a time to say goodbye.

I am not going anywhere without you!

7. But it is all worth it, so that you can finally reunite.

8. At which point, you go back to doing whatever it is you do.

9. Because through the years, you might get older, but you won't change -- whether that's for better...

10. ... or for worse.
