I remember a period in late adolescence when my mind would make itself drunk with images of adventurousness. This is how it will be when I grow up. I shall go there, do this, discover that, love her, and then her and her and her. I shall live as people in novels live and have lived. Which ones I was not sure, only that passion and danger, ecstasy and despair {but then more ecstasy} would be in attendance. However...who said that thing about "the littleness of life that art exaggerates"? There was a moment in my late twenties when I admitted that my adventurousness had long since petered out. I would never do those things adolescence had dreamt about. Instead, I mowed my lawn, I took holidays, I had my life.
But time...how time first grounds us and then confounds us. We thought we were being mature when we were only being safe. We imagined we were being responsible but we were only being cowardly. What we called realism turned out to be a way of avoiding things rather than facing them. Time...give us enough time and our best-supported decisions will seem wobbly, our certainties whimsical.
