With no previous problem of this nature, my husband got up at 7am, came downstairs to find me and said: "Is this morning or afternoon?" I honestly thought he was messing around and laughed - but no, he said again: "Is this the morning or afternoon, I really can't make it out." I confirmed that it was morning and I made him some tea and toast for breakfast. I was working from home today and able to keep an eye on things - but to be honest he showed no more sign of confusion and seemed quite content. For a long time now he has struggled telling the time, working out how much time has passed or how long it will take him to get to and from places - but not being able to tell morning and afternoon apart is a new one. I knew it would come but it still amazes me how these things can practically surface overnight. Maybe it is a one off and tomorrow he will know the difference. At least it doesn't seem to have caused him any distress.
