When I was 11 or so, I once led a group of friends in a game of follow-the-leader. I led them down to the creek and along the sand banks, jumping over the occasional log and muddy patch. On our return trip, I was astonished to run into a goodly number of copperheads coiled up cozily on these same sandy benches. With a combination of screams, shouts and agile dance moves, we all made it home safely.
I think romantic relationships are a lot like this.
