You will naturally take on the role of guide or mentor in this relationship. This should be a comfortable dynamic for both of you. Your friend has a lot to learn from you, and they'll actually want to learn these lessons.
Your friendship will be grounded in practicality, and you'll both understand and accept the type of communication style you share. This is because you'll both understand that the bond between you runs deep and true, and doesn't need qualification or even reiteration. Precisely because you won't push one another to be someone you're not, you'll be able to grow as individuals in a natural way through the course of the friendship. After all, you both have something to offer the other -- you can offer that life experience and knowledge that your buddy lacks, and they can offer you a sense of freshness and vitality that keeps the relationship new and exciting.
