I've watched the video and read the Facebook post and conclude that mother is just awful.
She put her daughter in that position, through her own disorganisation and assumptions. Nobody else.
She took absolutely no responsibility for the risk she took, and made a huge public song and dance with no regard for her 15-year old's dignity.
No wonder the poor girl and her dad looked so defeated.
I'm not surprised to read the mother has form for this.
