I'm right there with you AG, and now, so is one of my daughters.
It was an innocuous phone call. She rang her nanna, who was making her dinner. "Oh I hope you'll enjoy it" says my daughter. "It's only a corned beef sandwich" replies mum. So daughter says laughingly to jazz it up with salt and pepper, to which mum says, "I've got that stuff on it, what is it? That stuff you know, it's red, I think" daughter says distractingly, "well make it special - cut it into triangles" Mum says "Oh I don't know about that, don't want to be getting ideas above my station!" They both giggle and end the call. Daughter rings me upset because she can't understand how mum can quip that way yet not remember that "the red stuff" she puts on her sandwiches (every single day without fail, for about 4 years!) is cranberry sauce.
I just got back from mums, she was coming across as very lucid, then started on a tale of how she had been into Manchester this morning and had a run-in with a traffic warden (she has never driven and not been into Manchester for a couple of years!). Then as if that convo hadn't happened, returned to the topic we had previously been talking about!
She is clueless, my head is spinning on the other hand!
