Am really concerned about MIL, not sure what to do with this situation, we have arranged for someone to call to help fill in attendance allowance forms it was booked for yesterday but I had to cancel it until nexted week due to me having a hospital appointment, anyway the man still turned up at MIL yesterday after 25 mins the man phoned and asked where I was as he knew I wanted to be there because of her memory problem he soon realised his mistake and said he would call back next week. But I phoned my OH and told him and said I was concerned that she let the man in not really knowing who he was, anyway when he got to his mums, and this is what is really worring me she was adamant that no-one had been there and got angry when he doubted her, he really thought I had got it wrong, when I went to see her today she did say what I had said rang a bell but still wasn't really sure, but how can we stop her from letting strangers in. She did this about 5 years ago and her bag was stolen but luckily it was the one with nothing of valuable in. Will be grateful for any input.
