As an ex senior teacher then, sherrardk, you will obviously be aware of the disruption that unnecessary absences cause in class, be they among exam year pupils or others. You will also be aware of the that those more gullible children who see their classmates disappear to the Caribbean or Majorca for a fortnight see no difference between that and them disappearing to roam round the local shopping centre for a similar period. Finally, you will also know that such absences at fee-paying schools are virtually unheard of because, in the case of the young lady who is the subject of this question, two weeks off would have meant she had paid something like £500-£600 in fees for which her child had received no education.
The lady clearly gave her £8k ostentatious wedding higher priority than the educational needs of her child and I hope she pays a proper price to maintain her "principles".
