Through the natural support and kinship that you'd give to any close friend, you'll help this pal map out their best future path. Your support will give them the strength they need to move forward in life, and your friendship will serve as a solid base from which they can move outward into the world. You'll actually help them to access parts of themselves that they haven't been in touch with before.
You'll help them to figure out what's most important to them in terms of their values and their expectations for their future. They might even feel as if you were meant to come into their life, and you may well have been. You'll probably love feeling so wise and needed, because this friendship will really put a focus on all of your best qualities.
