The impression

I was walking with my friends through the city when an explosion was heard in the distance, muffled by the buildings and noise of cars. A shaven-headed girl that was walking in the opposite direction -she was wearing giant headphones- seemed oblivious to what had happened. The ground shook slightly and then she stopped. She must have felt dizzy because she tried in vain to hold on to the air. I reached out and grabbed her crazy forearm. I looked into her eyes first, then his mouth. The round expression on her lips anticipated a scream.
