We had the incident of her needing apparatus to do the number puzzles we had sent. I had sent her another large format word search book (Not a number book), and two boxes of pencils, wich had erasers on the top. [ I'm not sure whether the missing apparatus was the pencils or whether she hadn't realised that the oencils have erasers on the top. She'd asked for erasers because she'd got into the habit of obliterating the letters completely when she found a word...which meant she couldn't see those letters any more when searching for other words.
She now refers to the home as "Work" or "the Office". So, she'll tell us about things that happened at work today, or that the office has been rearranged. It doesn't matter, we know what she means.
We don't correct her, there's no point.
She gets upset that her daughter doesn't visit. Except, of course, my SIL does visit. In today's phone call, DH was explaining that his sister had been to visit at the weekend. This was strongly denied. "She brought you a television", DH continued.
DMIL was adamant that she doesn't have a television.
She does, of course. SIL and her hubby installed it at the weekend.
