But....You left one thing out.
The Child.
The Child.
The child is implicitly hostage/supportive to the woman's conduct. Would you let a terrorist live in the US simply because the child over which it has control need an American education? I don't think so.
The school made attempts to accommodate the child. However, for the child to attend the school, the mother must abide by the agreement she signed. It is the mother, not the school, who is "harming" the child.
