Here's something not discussed so far: bedroom size, because I think our set up was probably unusual. Ours was a big Edwardian house, the sort which was often divided into flats; I didn't realise until later how lovely it was compared to modern houses.
I had a massive bedroom, bigger than anybody else's, including my parents' bedroom. I probably didn't deserve it, because I never kept it tidy - this was an ongoing battle. My younger brother had a smaller room, and my parents' bedroom was about the same size as his. Only my mum kept her clothes in their bedroom - my dad used our attic as his "dressing room", and his wardrobe was kept there. This attic was reached by a proper door, not a trap door, but it was unfurnished, i.e. unpainted walls, sloping ceiling, no fitted carpet, tiny window, visible rafters, and mostly used for storing things. Not once did my parents threaten to move me to a smaller room for not keeping my bedroom tidy, which would probably have been the Mumsnet "consequence".
