A walk in the park

My mother and I were going on a walk to our neighborhood park with our dog. We were pleasantly surprised to see a friendly (though unleashed) dog that began walking alongside us to the park. We were having a good time. Suddenly along the way, we see a middle aged woman walking from the distance. The unleashed dog started to approach the woman (causing no harm whatsoever). The woman immediately began to make disgusted and angry facial expressions towards us. She quickly yelled at us "get your dog away from me, NOW!" We responded to the woman and tried explaining how the dog wasn't ours. She immediately cuts us off and things escalated quickly. Out of nowhere, her voice was exponentially louder screaming, "I SAID, GET THAT THAT F----N DOG AWAY FROM ME, YOU CH-NK. GO BACK TO CHINA OR WHEREVER THE F-CK YOU’RE FROM." "EVEN BETTER, WHY DON'T YOU GO CUT YOUR DOG UP TO SLICES AND EAT IT" My mom and I were startled, speechless and just shook. We tried walking away, but she started to follow us to the park and repeated those phrases multiple times what seemed like for another several minutes. She finally stopped after we kept walking away.
