Someone I knew wrote a really moving piece about how actually getting to know someone is like having the separating wall of glass between you suddenly lifted. About how it can take your breath away and surprise you with its honesty, and how difficult it is to ever achieve that sort of familiarity with anyone.

I think I've known a small handful of people like that in my life, even among those I've been romantically attached to. It's a connection worth striving towards. 

They say when you're more biologically compatible with someone, they smell better to you in particular than they would to anyone else. What does it mean if somebody smells better than anything?
