Stupid idiots

I deal with stupid idiots all day long. My coworkers and my clients. My coworkers like to make fun of my Chinese name. They know I have a English name. They do on purpose. Then they will say something stupid like Ching Chong blah blah. I try to explain to my coworkers all yellow skin people are not Chinese. You can't not call them Chinese cause they have yellow skin. You don't know what they are you have to say they are Asians. Smh
