AIBU to think School Prom for 11 yr old is getting out of hand??

It is wrong and also disgusting that in this climate of many who are struggling that things like this which blatantly show the haves and have-nots are becoming a common feature to further distress many parents and create very visible divisions between the two.

Pushy, showy-off parents are a scourge ! Horrible. What happens when these parents come to a sticky end ?

No, you are not being unreasonable. Unfortunately, until the school and headteachers crack down on some of the excesses we will continue to see this kind of nonsense.

A party to celebrate the end of primary school is not unreasonable but I suspect all the children would enjoy it just as much if they wore jeans and t-shirts.

It's great to hear from new posters - welcome!
You are not being unreasonable - The world has gone mad! Kiddies are no longer able to be kiddies! It is all over the top American pressure in my opinion.
