You'll have a creative connection, one that will encourage you to express yourselves in a deep and honest way. You, especially, might be used to more superficial friendships, but this person won't allow your bond to exist on anything but a deep, intense and focused level. This person will definitely encourage you to think more deeply and honestly, and the thoughts you come up with might surprise you.
You'll have a strong pull on them as well, though, don't worry. You can help them to translate their more abstract, heavy theories or impressions into terms that make sense. Even more importantly, you can encourage them to lighten up from time to time. But don't try to keep things too light; that would be letting a great opportunity slip by. Instead, you should really try to keep each other motivated in pursuing all those deep, dark and interesting ideas and bringing them to light.
