it all begins like this
I was riding around on my bike today. The traffic was a snarly mess but I easily sped around most of the cars. When I was almost back home, a car slowed down next to me. I slowed down because I wanted to make a left hand turn and wanted him to go through the intersection first. He lowered his window so I figured he was another lost tourist but all he said to me was "you need a helmet" and then sped off. Needless to say I was flabbergasted. There's no law requiring helmets and I was riding my bike carefully. I'm guessing there's a genetic predisposition to busy-bodyness in some people.
