You have my complete sympathy Luckylegs. And before Grandad leaps in, it is difficult for anyone out of their confort zone being asked to do tasks they are not used to, whether that is shopping, cleaning, washing, ironing, or anything else now required of them.
After a hysterectomy I had to ring up neighbours and plead with them to take DH out for a drink before I strangled him, and in these lockdown days even that isn't possible.
I find you have to be very explicit as to what you are actually asking them to do, don't ever assume common sense will prevail, because their idea of common sense may not be yours. And take yourself off to another room with an escapist book to wind down - or let off steam on here!
