My SIL, in her 30s, still lives at home with her parents. MIL is just shy of 60 and has smoked since she was 12; she is in poor health. FIL is turning 70 in a few days and has heart problems (along with other medical issues).
SIL works as a GP receptionist. Obviously she can't avoid all contact with patients and is a likely vector for infection. The house is small and MIL sleeps on the living room sofa as for years she's been unable to get to sleep in the same bed as FIL. There's only one toilet. It'd be hard or impossible for anyone to isolate from other members of the household.
MIL seems to get that it is serious. SIL does not. She keeps complaining about how OTT the government is, how it's just like flu, how silly it is to make a fuss. She alternates between saying everyone will get it so there's no point taking precautions, and claiming it's not very contagious so we don't need to worry. She's said they've had no symptoms so they're all fine, while simultaneously telling us that she's heard you often have no symptoms even if you have the virus (no shit). We just found out that yesterday SIL took both elderly parents to Tesco. There were hour-long queues to get in and it was a scrum inside. They didn't actually need to buy anything but went anyway, just in case.
SIL is in charge of other people at her work and was mocking them asking to put their desks further away from one another, as she's sure we'll all get it anyway. She washes her hands, but doesn't like to use sanitiser as it dries her skin.
I am right at the end of my tether with her. We tried to talk to her about it today; she was busy saying how silly it is they've closed Old People's Homes to visitors as surely it would be lonely? Tried to suggest maybe it'd be an idea to just eat food in the house (FIL is a hoarder; there is food for an army for months), and she said they had to go out because 'the stockpilers' are stealing all the food.
ARGH.
Please tell me this idiocy is not just mine to deal with?!
