person A: Yesterday I walked through the park to get some fresh air. I saw a mother beating up her kid in the park. I can't believe that some people really will do that.
person B: That sounds aggravating. Did you say anything to her?
person A: No I had no idea what to say at the time. And worried that she might turn on me.
person B: Thats okay_comma_ you should call the police next time.
