Weird Thing

So there is this weird thing happening, which is, more and more I am unable to see the Asian-ness in my students' faces.  Like, some of them, I look at them and I can't even fathom how they are Chinese.  There is this one student in one of my freshman classes who is pretty hip-looking, with cool glasses and done-up hair, and for some reason I look at her and she looks completely American to me.  I can't remember what I thought of her the first time I saw her but now, I see no signs of Asian appearance even though I'm sure she must look Asian.  And the pre-masters students I see twice a week, and there are only 15 people in the class so I know most of them personally, and I spend so much time speaking in English with them that when we are out of class and they turn to each other and say something in Chinese, it is almost shocking to me.  Like I feel surprised and like it is unnatural that they should be speaking something other than English.  And sometimes I will sit in class while they're doing something and stare at their faces and try to imagine how they look Chinese.  Some of them do but some of them, I just can't pick out signs of ...difference.  Weird!!
Probably, ya'll are gonna look foreign to me when I get back...
