I guess that is exactly what I was trying to say GillT57 - it is possible to conflate small things into issues of principle (respect etc.) when really they are tiny in the scheme of things. Extrapolating such a small thing into an issue of respect is what is known as catastrophising in my book.
Sorry bags if I sound critical - I am coming from a very different place from you on this issue, but it might be a different view to at least consider. If she does not respond to the tongue-in-cheek dirty bowl in the bed (which should be done with a bit of humour), then I should just cut her a bit of slack - you do not want to provide her with a battle ground unnecessarily - there will be plenty more serious ones to come.
I had 3 teenage girls in my house at one point - and survived! I let an awful lot flow by me, but made sure that there were lots of hugs and that these were the important things. They came round to these details in their own time.
Anyone yet watched the ITV Reform “expose”

]but imo teenagers that work hard at school and are generally nice and polite to people have to let rip in some ways, even if it's just leaving crumbs lying around. Strangely enough [on the subject of crumbs] although I live in absolute squalor when I have something to eat out I always have to put everything neatly back on the tray or, if I'm in a group of people have to stack the plates nicely [probably a result of years of waitressing]. When I worked at a surgery I was always amazed by mothers/fathers that let their children get the books and toys out of the box but never got them to put them back afterwards. I always felt that the ones that did that probably had immaculate homes. My kids always tidied up after themselve when out and about but at home it was the usual chaos.
for you too
