Hmmm... when I went to school, girls were sent home for similar reasons. But that was then and this is modern society!

Now, the thing to do is to get another boy to wear eyeliner in her class (not so obviuos - like tomorrow) and see how she responds. If she allows him to remain in class without a word, then your friend has a valid complaint.

Has your friend's grandmother spoken to the teacher? I have had to go to my kids school for various reasons (one thing I've learned is to never ever go storming in a blaming the teacher... always go in to "discuss the matter and get both sides of the story.")

I had one teacher that was being blatantly unfair to my daughter last year (she almost got suspended for laughing during a game in class - even after the teacher admitted she was encouraging laughter!) We took it all the way to the superintendant and my daughter got pulled out of the class and into a new one.

Personally, I'm too old fashioned to like the look of makeup on males, but that's me. I realize that its a whole lot better form of personal expression than permanent tatoos, so with the choice, I'd say put all of the eyeliner on you want and stay away from permanently marking your body!
