Safety first!

I was sitting on the subway yesterday zoning out and wondering absently what video game the guy next to me was playing on his phone when he looked over at me. “So you really like bike riding, huh,” he said. I wondered if he’d seen me lock up my bike before getting on the train. Or maybe he could just tell I like to ride bikes? Or maybe he was just a little crazy? But then I reached up to my hair and realized my helmet was still buckled around my head.
