I’m a white blonde female, but I grew up learning Spanish and ended up living in Chile and Mexico for a time. I am pretty fluent in Spanish. I was 18 and getting my car fixed after an accident and I had to walk around back with one of the guys past the garage where all the mechanics were. This was in Arizona so almost everyone working there was Mexican or Hispanic. They started saying some really rude things about me in Spanish loudly and they were laughing. I understood them but was too embarrassed to say anything. With me being white they probably assumed I didn’t understand them. After my car was done I walked back around past the guys again. This time one of them said something along the lines of “I want to kill her with my di*k/ choke her”.... something like that. At that point I decided to turn and tell him off in Spanish and say that yes, I understood him, and I let him know how rude, offensive, and uncalled for that was. My Spanish isn’t perfect, and I probably didn’t get the exact point across that I wanted to because I was nervous and angry, but he and the coworkers clearly understood that I had heard them and knew exactly what they were saying. On my way home I called the car place and told the manager what happened and he said he would handle it. Idk what happened after that but I was young and shy and was proud of myself for how I handled it in the moment.
