A friend that will "rise from the ashes" (the debris of your fuck up) and come to stand by your side. Stick with you through all of your mistakes, flame wars, and rough patches. The ones that are always there for you no matter what. The very best kind of friend. Even if you hurt them, they'll still end up being there for you. They can widthstand the flames of tough times and still manage to cheer you up and stick up for you.
You- "Going through a really rough time right now."
Pheonix Friend- "It's ok, you know that no matter what I'll always be on your side. I'm here for you."
