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.
