I live in Japan. I have no car. Pretty much any time I want to go somewhere, I ride my bike. My bike...is not a good bike. It started rusting within a month despite having been kept under an awning, so the chain makes a horrendous creaking noise every time I pedal.
Well, the other night I was screeching along down the sidewalk and there was a high wall to my left causing weird echoes. I THOUGHT that I heard someone behind me, and sure enough when I glanced over my shoulder, I saw some girl's shadow. I was going a decent speed, but I hugged the wall a little closer to let her pass. 30 seconds later, I was starting to get annoyed by the fact that she was still closely following me but steadfastly refusing to pass. Finally I stopped my bike completely and turned, expecting someone to dodge around me and continue on their way...only to realize that I'd been waiting for my own damn shadow to pass.
Good news: I've apparently lost enough weight that I no longer recognize my own silhouette. Bad news: I'm an idiot.
