Yeah so let me break this down with crayons so you understand me and context +Rosepher Catervas
The father was wrong, in that the dress code does not need to be changed. b
The father is wrong, because the teacher was wrong and over stepped authority they didn't have. c
The dress code doesn't need to be changed. It's fine the way it is. The teacher was wrong, period. End of story. d
Anyone that says the kid violated the dress code, didn't read the article. It's really plainly put in the article.
Now does this answer your questions Rosepher, or do I need to explain more plainly?
