She and I were standing there a few feet from the edge of the roof.  She had just remarked about our height above the streets and sidewalks of New York (we were on the 21st floor), and I mentioned something of fear.  It was a sort of strange thing, but between my words trailing off and her response, I found myself walking closer to the edge until my toes hung off the concrete.  Then I stuck my head out ahead of my body and peered down. confused, she asked from behind me, “what are you doing?”  I suddenly shifted my weight backwards and took a step away from the edge - realizing, I didn’t trust my balance,  I didn’t trust the wind, and I couldn’t trust her not to push.
