Crescent moon

A few weeks ago I saw a crescent moon. It seemed like for the first time ever I viewed the slight moon as three dimensional - knowing that the sliver was simply a portion of the fully illuminated moon surface. I could immediately sense the rest of the sunny side fully ablaze in light. The slim moon suddenly had depth to it that I had never before known.

I wondered, how many other times in life do we see only a portion of the big picture? Sometimes seeing it years later, probably many times never seeing it at all.
