BFF stands for Best Friend Forever, to me a BFF always has your back and is with you through everything. Having a best friend should be like having a brother or sister. Sure you'll have fights ,but you'll always make up. A best friend is someone you can't live without someone that fills a void in your life, someone who cares about you and who you care about. You shall have the strongest bonds that no one can sever. You may go in some of the best journeys in life together and have the best experiences while in each other's company. A BFF is a true friend you will have forever.

I known my BFF for 20 years and have had a lot of fantastic fun on vacations with her.

BFF 

Your "Best Friend Forever". Someone you know you can trust. A sibling from another parent. The one friend you hang out with the most. Someone who will laugh when you laugh, cry when you cry, and smile when you smile. They will stand up for you, and they will listen when you blab on and on about all of life's problems.

I can tell my "BFF" anything in the world, and they will listen.
