My nieces go to posh private schools (same school as the Princesses Eugenie and Beatrice), and one of them posted on FB photos of a day they had spent at school dressed as tramps - they made a shelter in the classroom (inside obviously in case they got cold!) and one of them had drawn a beard on herself. It all looked great fun and jolly hockeysticks, but I think they could have got the girls down to the local Salvation Army shelter to hand out some soup or clean a hostel or something instead. I know going to a private school is because the parents are terrified their girls won't cope in the rough inner city that is Windsor (!!!!) but this level of role play is sick making. What on earth did they get out of this, except to have great larks, what ho!! I could just hear their posh voices chirping away!!
