True best friends don't just come knocking on your door every day. They are a once-in-a-lifetime find you need to hold onto tight. You may have a bunch of good friends, but a forever friend is totally different. You can tell the difference because your bestie feels more like family and they can pretty much read your mind. There are more than a few words that describe best friends that prove that you're the forever type.
You know right away once you've locked down your BFF, because the minute they walk into your life, it's like something instantly clicks. You finally find that missing puzzle piece that makes you feel complete. You have someone to tell all of your secrets to, who's down for any spontaneous adventure, has a similar (if not the same) sense of humor, and just gets you like no one else does. That's why they're so special.
You also completely understand these 10 adjectives whenever your BFF is around, which proves your friendship is the real deal. You may not get these qualities in each one of your friendships, but your bestie is checking off all the boxes. That is why she qualifies for that "forever" piece of best friends forever.
