The knock-on effect closing schools down will be astronomical, and for a fuck ton of households, school work will be way down the list of things to give a shit about.
I'm not saying I don't care about my child's education. Of course, I do. That shit can be dealt with afterwards.
And although I could technically take in loads of extra children. I will not be. Instead, I will help friends in other ways if I can, but inviting all those extra 'carriers' into my home daily, nope, fuck that.
I would advise anyone to really think about this offer before you make it, it's a nice gesture, but....
Aside from the extra 'carriers' what if one of them tests positive? Worst-case scenario, someone in your house gets tested positive and potentially you have a lot of kids on your hands over a long term period. Same with if any of their parents test positive.
And if anyone is asked and you don't want to do, tell them no. They probably won't like it. But for your own health of yourself and family, think very, very hard.
