I think this begs the question, "what is meant by 'self-isolate'?"
My DD's partner had to "self-isolate" but they just took that to mean, "stay at home" so they were still sharing a bed, sharing a bathroom (they only have one) sharing child care so both in daily, close physical contact with her as she's only 5, sharing a kitchen, cooking meals for each other, etc. etc. I contend that this isn't self isolation and that, therefore, my DD should also have been off work and the child off school.
What is the point of all this so called, "self-isolation if not?
Totally different for those PPs have described as being shut in their rooms, meals on trays, separate bathrooms etc. I get that totally but how many, "self-isolators" are actually doing that? I'm becoming so disillusioned with the measures being taken, or not taken, in the feeble attempts to stem this pandemic.
