Never believed it would happen to us too

My father (64 years old, Chinese immigrant from Malaysia) took a walk outside his neighborhood in Duluth, GA, as he does regularly, to the gas station. He noticed a young man (late twenties to thirties) who was sitting on a bench outside of the courthouse/police station (my father at the time thought this was city hall), as he walked pass him, he didn't say anything. As my father was walking back, he noticed that the young man was standing up in the walkway by the parking lot. My father looked the man in his eyes, nodded, smiled, and said hello. The man started to verbally curse him out, my dad had earphones on listening to Chinese news. He said he couldn't make out exactly what the young man said - but somewhere along the lines of, "Motherf*cker, I don't need your respect," and kept yelling. My dad is not fluent in English, but knows enough. The man approached my dad and pushed him, my father pushed him back and put his fists up, the man kept approaching him, but my dad kept walking backwards. The man eventually stopped approaching him and my dad looked back to see if he was being followed. He was not followed and he made it home safely. My dad had been hearing news of this happening, but never believed that this would happen to him.
