You'll come in contact for a bigger purpose, a spiritual ideal. If you tend to be a cynical, pessimistic type (though you might call yourself realistic!), this friendship will help you open up your soul a little bit and soften that hardened shell you've developed. After all, your cynicism is just a defense mechanism you've developed as a response to various experiences that life has served up for you; it's not necessarily an accurate representation of the way the world really works.
This friendship will help to open you back up to the intangible side of life and human possibility. Your pal will help you to start to believe in magic again, and you, in return, will help them to stay grounded in reality. You might simply enrich each other's lives with your complementary perspectives, but you could also get into something more specific and directed in terms of spirituality.
