I'm coming at this from a school's point of view, and from Manchester, but please listen because where I am this situation is now ridiculous.
At school kids don't socially distance, not because it is safe, but because we done have the resources to distance, so we have this shit idea of a bubble. Every time a child interacts with another, it is a risk. We really what all other interactions outside of school to stop, because it will decrease the overall risk, because every single interaction is a risk. Just because "they are in a bubble" and "they are together all day anyway" doesn't make your party any safer.
I've explained this to my 6th formers using the concept of tokens. Imagine you have 100 for the week, and every time you are in touching distance with someone you use one up. You will quickly use them up in school, and if you use them outside of school you might run out before the end of the week, therefore you are out of tokens. When you are out of tokens, you have ran out of the statistically safe interactions.
So many people have said they'd do anything to keep schools open safely, but I'm seeing none of that. And yet we keep having kids turb up to school with symptoms, we get told of parties and visits to grandparents and we have increasing levels of infections and now we are seeing increased deaths.
I'm pleased you can all legally mix right now, but I can't. I am a giant risk to my family. I hope to see my parents at the very end of my 2 week october half term so I can completely isolate for 2 weeks before hand.
Please, can we do what we said and do anything and everything to keep schools open? We are already sick of sending bubbles home.
