"I promise to love you, unconditionally, through every high, low, peak and valley life takes us through."
~23 promises you should make to your best friend

This was in an article I saw. It was an amazingly powerful article, I truly enjoyed it.

Your best friend is there for you, think and through, and they will never let you down. Covet your relationship. And love them, through anything you go through, because that love will keep you strong.
