Portable radio on shelf outside door playing radio one. If the music stops then someone has turned it off - otherwise it masks any conversation.

I don't always agree with you, but this time...

It may be longer than that too.

My father BTW once said "If I was a dog you'd shoot me". Even if your mind holds out it can get too much.

If she gets as ill as my Grandads wife (Meg) did with her dementia then a water sensor on the floor outside the room would have done the trick:-(.

I don't know the answer - but best of luck.

And remember the old saying our family had "Meg does not suffer from dementia, only Grandad does".

You write "Meg does not suffer from dementia, only Grandad does". Ain't that the truth!
