My grandparents known as Nan and Grandad lived in a 'posh' council house with front parlour, sitting room, kitchen, pantry and scullery. My Aunt lived in the next street, thought to be less 'posh' and had a kitchen,where they had a 3 piece suite and a back kitchen where they ate tea in the evening. My parents bought their own brand new semi in the suburbs, my mum was very proud of her lounge with sliding doors to the dining room and a kitchen with some fitted units. My children called them Nan and Grandad. When I married we moved to the countryside and, without awareness or thought until today, I realise we have a sitting room, dining room, kitchen and sun room. We have sofas in the sitting room, we eat lunch in the middle of the day and dinner in the evening and when did my children start calling my parents Gran and Grandpa, didn't even notice. Changing times.
