Yeah - that book "U and non-U" was by Nancy Mitford, it told you helpful things like which was "correct" to say like serviette or napkin (I don't think she even would have known about "do you want a bit of kitchen roll with that?"!).
they were superb dg, my mum used to whiten my shoes for Sunday School and put them in the cupboard at the side to dry and the dough used to on the hearth with cloth over it for the bread
i still call a kitchen a kitchen, but our 'utility room', we call the scullery.
and we call our.... erm, where we hang our jackets up and shoes etc... we call that the vestibule!!
Another reason for not using the front room was that was where you would put a open coffin for all the mourners to look a the deceased . And you would not want to have all your relatives think that your where not well off bye having worn out carpets or scruffy furniture.
funny dusty....we never called it that.
I went to my best mates once in the 60's and walked through the front room into the living kitchen.....it was only on the way out that I noticed her father laid out in his coffin in the front room..............no-one had mentioned it.
