"We all just kept on walking."

A lady in the subway station was walking toward me with her mask down, made eye contact, said, "F*cking Asian." She then shouldered me. While not so strong that I fell, it was forceful enough to twist my torso around and make me do a half step to stay upright. I yelled back, "What the f*ck?" Two other people saw the incident but we all just kept on walking. It was a quick interaction since I was mostly concerned with catching the train and no major physical contact or issues occurred. Thank you for this space to report an incident that would otherwise go undocumented.
