OP if your DC and surrounding adults are following the rules, then your opening post makes no sense 
Why would you want to risk what you and your family have achieved by packing your kid off to school to mingle with the fuckwits?
Yes I get pissed off when my teenage DD is sobbing because her friends are sneaking off to meet up. I am in Scotland so going to a park etc still not allowed.
But I also held her while she sobbed when the exams were cancelled as she didn't do well in her prelims.
I gently remind her that pain has to be worth something.
What sort of education do you think will be provided? it won't be anything like before.
Can you actually imagine what the atmosphere in a secondary school will like? School should be a welcoming environment, a constant a safe space.
"He coughed on me". "She's deliberately coming too close". The teenagers who have complied will continue to and those who haven't will also continue to.
The amount of cases is higher than it was when we closed the schools. I cannot see why it would now be safe to open them.
