Name Mistaken

In one of my classes, I was mistaken for the only other black woman in my class. This was done by a student when trying to reference a point I had brought up in the previous class discussion two days before. This point he was trying to reference was said in a twenty minute presentation I had given last class. This other black woman and I have two vastly different skin tones and were sporting two very different hairstyles. When I corrected him on who he was trying to quote, he waved it off and perhaps spared me two seconds of eye contact. I was annoyed the entirety of the class period and looking back, I wish I had stood up for myself a bit more. Your dismissal of knowing my name is simultaneously you participating in the erasure of black women in academia.
