Good grief is right.
It reminds me of a children's book years ago. (In the age of perms, curly hair was frowned upon and it had to be kept tidy by pulling back.)
I went to a school with a dress code. No shorts, sun dresses, tanks or bare midriffs. No facial hair on the guys. Oh, guys' hair couldn't hit longer than the color. No Tshirs with logos. No tattoos. And skirts couldn't be too short or they would make you sit in the office and make your mom bring you decent clothes.. I had friends who were marked down for having dreds and natural hair. Boring? Yeah. Good high school. You betcha. But the red. hair thing is way out there.
One reason kids have the attention span of ants (or is it gnats?): electronics, internet and social media. No wonder it's easy to distract them. Research has been done on this.
Regarding the hair:
How archaic! Red hair has been frowned upon for centuries. It was the mark of "ladies of the evening" and no self-respecting woman would have red hair. Of course, back then if you were a natural redhead, who would know? Women kept their heads covered until the mid-19th century.
So here is 2014 and they picking at the girl's hair? Be glad she wants to go to school. The kids are probably used to it and don't notice.
