Significance of firefighters carrying hats in parade?
I was downtown today and stumbled upon a parade of firefighters. Most of them were wearing dress uniforms, including dress hats. Some of them, however, were also holding the hard hats that they wear when they fight fires. Do you think that they are carrying their own hats—or, are they maybe carrying the hats of their fallen brothers and sisters?
