Aneeba, my mother was the same, wanting to go home to parents who’d been dead 30 odd and 50 odd years - the house didn’t even exist any more. She’d say, ‘They must be getting old and could do with some help.’
By then I was very adept at ‘love lies’! I used to say I couldn’t take her today, because the roads were very icy/closed because of a bad accident/my car was being serviced/you name it, ‘But maybe we could go tomorrow?’
That always kept her happy, or at least reasonably contented.
Now and then I’d even add that I’d give them a ring later to make sure they’d be in, because, ‘We wouldn’t want to go all that way and find them out, would we?’
It was a bit scary how I could trot this sort of thing out, ad lib!
