I think the more people have, the more extravagant they have to get to have something special and this has fuelled the prom madness.
When I left school in the early 1960s, we did not have any celebration or commemoration at all. For me, just walking out of the school premises knowing I would never go there again as a pupil was celebration enough.
DGC have managed to get through nursery, preschool, reception and KS1 without anything special at all. However the school do have 'Wow' assemblies when a several children in each class get commended and applauded for anything from good work to good behaviour (I think every child gets a Wow assembly for something at some point)
Any way, last week it was DGS turn. He was commended for being a model pupil, well behaved, an example to all. At which point DDiL who was trying to match this model child, to the child she actually lived with, accidentally let out a huge snort. At which everyone turned and most of the adults, including teachers, had to bite back giggles.
