So I have to teach this class of kids but I can't tell half of them apart. Half of the kids on the class are white boys with brown short hair. They are all thin, about the same height, and none of them wear glasses. I've sort of always had this issue telling white people apart, which is weird because I am 3/4 white. Everyone in my family looks so different, so I was used to using hair color, skin color, and gender to tell who was who.
