Brain Death Is No Laughing Matter

This morning, while careening my bike masterfully through a particularly thorny intersection, taking care to let a pedestrian pass in front of me before threading the needle through the crowd, said pedestrian did yell:

Brain-dead! Look where you're going!!!!

I would like it to be acknowledged that this kind of name-calling was not necessary. I was so very closely looking where I was going. I was so very much brain-alive that I was specifically taking care to protect this very pedestrian's right of way. I was on my way to copy-edit, an activity that takes no small amount of brain power. I don't have to tell you that I now wish I had maybe run over this guy's foot.
