Your thoughts, ideas and conversations will take on a deep sort of intensity with this friend, and you may talk about extreme or taboo subjects. They might try to dominate the conversation or even your way of thinking -- especially if things veer toward small talk. There are too many big, life-and-death issues to discuss to waste time chitchatting, at least to their mind.
If your pal has an idea that's abstract or otherwise complicated, you'll be able to give it rational expression. Your effect on each other will be big. If you were to end up working together on a business or creative project, this would be a really advantageous connection, because it will allow you to bring your deepest thoughts out to light. But even in your day-to-day interactions, you'll feel the effects of this pull between you. You'll broaden each other's horizons by introducing subjects the other might never have considered before.
