Occasionally a student gets a little huffy that I don't remember her name. (It's always a girl, I assume because I'm a cute guy and being huffy is what 15-year old girls do. Anna says it's because they all have crushes on me.) They also complain that I have an easier time remembering the boys. I explain that not only do I have 270 students, who I see an hour a week or less, but there are fewer boys (about 5:1 in my classes), and they have a wider variety of names. Most of my girls (black hair and dark brown eyes, with a handful of exceptions) are named:
Karina (3 in one class)
Camila (4 in one class)
Javiera (3 in one class)
And Helen and Hellen get annoyed when I pronounce their names wrong.
