Grandmother needs to start using the dishwasher, she evidently can no longer wash dishes by hand.
I visited my grandmother today, she served me some fried salmon and a bowl of ice cream. Afterwards, I observed how she washed the ice-cream-stained-bowl. She rinsed it with hot water, scrubbed it a bit, then some more hot water, then it was "clean".. no attempt to use soap at all (which I fully expected her to use)
Afterwards, I inspected her cup drawer... to my horror, almost 50% of the "clean" cups contained coffee stains or traces of whatever was there before washing.
When I pointed out to her that she needs to start using the dishwasher, she got angry, and angrily said
I have washed by hand for 80 years, so I'm sure as hell not going to start using a dishwasher now!
Well.. in my opinion, she's now a danger both to her own health and to whomever visitor she serves food.
I took this up with my mother, and mother has already been aware of this for some time, and said that "grandmother gets so angry and/or sad every time I mentioned it, so I have just given up..."
How can we convince grandmother to use the dishwasher?
