He tried to intimidate me on the sidewalk!
He stood in my way and said very loudly "you're not welcome here, sir"
I laughed at him and kept walking. He followed me for a few steps, I assume he was still trying to scare me?
We got to a crosswalk, so I waited for the light to change and watched him struggle to choose between trying to be intimidating and trying to pretend he wasn't following me.
He was clearly skirting on the edge of what's acceptable behavior in an attempt to provoke me, so that he could claim I was the aggressor. Typical abusive behavior.
