Oh and I also had to wear my private school uniform on a Sunday for chapel. It would never have been a boast because my school was my school, it was what I knew. It was a mixed bag of very wealthy people, people who worked hard and sacrificed a lot to pay the fees, kids on bursaries, kids on scholarships, kids on assisted places.
I privately educated my son, and yes it was the very best option in my area and yes we did without other things and lived in a small house for a long long time, and I had a very very old cheap car. That is my choice. I'm not sniffy when people spend money on a lavish life style and choose not to have a paid education. They obviously think they are doing their best for their children albeit in a different way.
I think the judgement comes from people assuming private schools are full of toffs so it's fine to poke them with a stick. Whereas actually I went to school with people from very down to earth backgrounds who just thought they were doing their best by their kids.
Sneer in judgement on their parenting choices if you wish, but don't try to take away their freedom to choose what they think is best. Or where do we stop? All drive the same car, own the same size TV, wear the same clothes? No separate cabins on planes and trains? One size of hotel room for all? Maybe go back to rationing?
The first post could have just been out of ignorance if the OP didn't realise lots of private schools have lessons and activities over the weekends but it has now become apparent it was just a pernicious attempt to pigeon hole young kids who've shockingly made the mistake to wear their school jumper when the OP deems they shouldn't so they must be toady little boastful snobs.
Sorry OP but private schools are not what you think they are, it really is your prejudice at work here. Maybe live and let live
