This evening, while watching tv, she suddenly said do you have a set like this at home?. Well i glossed over that and a bit later on, after we had dinner , she suddenly got up and when i said " are you ok" she said " i have get my husbands dinner ready". Her first husband is dead and we have been together for 44yrs. I carfully exspained that she was married to me and had been for a very long time and that he was dead. Oddly she excepted and even said " it's my brain playing up isn't it". So somewhere on some level she understands that something is out off kilter, and excepts that. I told her it was the problem she has with her brain, which did not seem to worry her.
