A lot of Americans say that Asians all look alike. Japanese, too, say that all Americans look a like–despite black, blond, or blue-eyed. Neither culture is correct, although people do share similar traits and characteristics. But I do teach about a thousand kids a year, and many kids have very similar names, looks, and styles. So I could only laugh when I got a sayonara note from a student that read, “I really enjoyed all the classes you taught, even though you often called me Risa instead of Rina.”
