Chinese?

A very Caucasian looking student in my class has been squinting all year.  And I don't just mean a bit... he looks up and squints to see me... he always has his nose in a book... literally, because he most likely has trouble seeing the words.  He sits at the very front, and I almost laugh every time he looks up and squints.  I told him he should see an optometrist, I've emailed home, I wrote in his report card comment this term.  
He comes to class the other day and says, "Mrs. ABC!  I know why I squint!"
"Oh really! Are you getting glasses?"
"Oh no, I found out I'm part Chinese, and they have squinty eyes, so that's why I squint!"

Sometimes I wonder if the word GULLIBLE or DUMB is written across my face!
