I was riding on a street today and some guy standing in front of his house started screaming, "Why not walk?" at me as well as "Get some exercise!"
I pointed to the car in his driveway and yelled back, "You have a car. Why don't YOU walk?" But he just repeated "Why not walk?"
I guess I probably can't call the police for this - I mean, screaming in public is free speech, right - but sometimes I wish I had some recourse against people like him.
