at junior school we used to have toy day where you could take yor fav toy into school and just play all day for the last day of year
at secondary school we used to have school discos which have mysteriously turned into things called proms which i find absolutely pathetic and yet another un needed peice of culture from the yanks
we also had rag day where you paid 50p to go to school in your normal clothes and this as far as i know still happens
instead of proms why not have a day trip to the job center so people can actualy say they have been to one
