On the edge of what? The edge of life? The edge of the photo? Who knows? We all feel on the edge at times. It might be fun or it might be excruciating. Some days are better than others.
Sometimes, being on the edge you may need a parachute. I don’t like being on the edge, not when it’s a stressful time. I would rather sit somewhere peaceful on my bench, by a river in the countryside somewhere.
