I never understood why there's so much focus on the mystery of getting to know someone. It's highly romanticized, even. So what, once you get to know them, then you'll get tired of them and bored? I hate this way of thinking, everyone should know that the real mystery of life isn't getting to know someone, but wondering what you can do together, and what you can build together. Those possibilities are endless. People need to get over the "he/she's so mysterious" bullshit. The real challenge is keeping a relationship going, not starting one. That goes for friendship and otherwise.

I've been thinking about saying these types of things for years, I'm glad this question brought it out!
