A best friend is more valuable than any money or treasure could ever be. They will be there for you through thick and thin. They will withhold their judgment when you're really not in a place to be judged, but they'll also give you a swift kick in the seat of your pants when you really need one. They will love and support you when others in your life make their affection contingent on you behaving a certain way or biting your tongue when you should speak up. They won't care if you make lots of money or live in the "right" neighborhood," because that's not what brought you together. Truly, a best friend is something that everyone deserves to have.
Going through life with your bestie is orders of magnitude easier than going through it alone. That's why it's so important to treasure the memories, from the screw-ups to the breakups to the straight-up ups (and the downs). Those are the fire that tempers the metal of your relationship and makes it strong, flexible, and capable of lasting a lifetime, no matter whether it began decades ago or just a couple of years. Tell us about your BFF, and we'll see when you first fell in friendly love!
