My dishes?

[Nexttimewillprobablybethesame]

I work from home.
I cook 95% of meals from scratch, taking between 30 mins to 60 mins daily. Washing/tidying up around 30 mins.
Occasionally, DH will ask one of the children to volunteer to wash up.
No more than once a month.
When the dishes are washed, I am notified with an, "I've finished washing YOUR dishes."
I am then expected to give thanks and praise for the generous sacrifice.
I wouldn't be so miffed if it was put, "the dishes are washed, thanks for tea".
AIBU to expect that in a family home, the dishes don't just belong to me, they belong to everyone?

Wow I wouldn’t be having that.

Tbh I'd make them do it every night

See also: "I've taken your rubbish out for you" "I've cleared the table for you" "I've vacuumed the sitting room for you"

Is it coming from your child? Then you need to express your thoughts and feelings to them. They won't magically learn it by themselves. If it's coming from the husband, he is a lost cause.
Incidentally, I always debate with myself whether or not to praise my 14 year old for doing the dishes. On one hand, I want her to know it is appreciated, on the other hand, I feel it may give her a message that she is doing us a favour.

YANBU. I even had a colleague like this once. We were working on a project together, and every time she finished a bit of her work she would say she had done it "for me" as though it was a favour, even though it was her effing job and we were able to work in parallel, so it's not even like there were any dependencies.

If your family think they are doing your dishes for you, start taking them literally and cook and clean for yourself only! (Perhaps talk to them first, though.)

'ok thanks, what did you do with everyone else's dishes?'

BTW, my teen DD thanks me for cooking, etc., I thank her for unloading the dishwasher, etc. I also thank her for feeding the cat, as that cat is an ungrateful sod...
