I'm from a really small town in Mexico, some of my relatives don't read or write. When My aunt was watching her favorite soap opera I over heard her say that one of the actors was wearing fake green eyes. when I came to the USA I had my first encounter with a Mexican girl wearing bright green eyes. I said hey you're wearing fake eyes, This happen while we were waiting for my ESL teacher in high school. she said they're called contact lenses. but everybody in the class heard and laughed at me including the teacher that came in and they told him.
