We've agreed that DS can have a disco for his 10th birthday and he wants the whole class except for 3 children 
. Tbh I don't blame him for wanting to exclude them as they are a total PITA and have made his (& many of his friends) lives a misery for the past 5 years of school BUT it just doesn't feel right excluding such a small number. If he were much younger I would say no, they either all come or we have the usual small number but is it fair to veto the entire idea just because of their behaviour. WWYD?
