Girl friend said it was because it was raining. However, the young man walking dog and others indicated heavy rain did not start untill after fight started.
Z reported him standing and staring at him (twice) Once with his hand in his belt.
I've never noticed my neighborhood's "hoodie wearing" population ducking in and out of doorways when it's raining. They'd be carrying umbrellas instead.
As an aside, I'm hearing a helicopter hovering nearby. I wonder what's going on.
