Racism. My daughter was talking about a kid at school, and I didn't recognize the name so she said "oh he's the one with frizzy hair and tan skin." I laughed and said "you mean he's black?" She said something about how he didn't look like other black people, and I said he's probably mixed. She misheard me, and answered "He's not mexican, he doesn't even have a mustache."
Now I'm picturing the guy in a cartoon mariachi band.

Thing is, she went to a school for awhile that was over 30% hispanic ESL students. Kids are weird.
