It's her place unfortunately so makes things difficult.
She's the most stubborn woman I've ever met - and that was pre-dementia - now I cannot suggest anything without being shot down in flames.
I've just picked her up from a friend who kindly took her to the theatre this evening. When she got in the car there was an overpowering smell of underarm odour. I asked if she had any deodorant and if she was using it but she said 'oh I can't be bothered with that'. When I pointed out she was pretty niffy she said she didn't care she couldn't smell it. Fab - I can but apparently I just have to put up with it. Wouldn't mind but the friend who took her out this evening has asked her to shower when she has turned up at her place before now and off she meekly goes to do as she's told. It's SO frustrating.
Sorry, went on a mini rant there - couldn't help myself. Apologies!
Is there any chance that her friend could help you by suggesting more often?
