At that moment, I wanted to isolate myself. I had not yet resolved anything, or reached any decision. I stood motionless, looking at the dark sky and the cold stars, pale ghosts of the stars that shone on Earth. My mind was a blank. All I had was the grim certainty of having crossed some point of no return. I refused to admit that I was travelling towards what I could not reach. Apathy robbed me of the strength even to despise myself.
...but leaving would mean giving up a chance, perhaps an infinitesimal one, perhaps only imaginary…Must I go on living here then, among the objects we both had touched, in the air she had breathed? In the name of what? In the hope of her return? I hoped for nothing. And yet I lived in expectation. Since she had gone, that was all that remained. I did not know what achievements, what mockery, even what tortures still awaited me. I knew nothing, and I persisted in the faith that the time of cruel miracles was not past.
