Inspired by my having rooms in my house called "horse's room"* *and "the pretend bedroom". I am surely not the only one to be this weird...
(Horse's room is actually a sort of study/craft room, but a hobby horse is stored there in amongst a load of rolls of wrapping paper, so apparently it's his room. The pretend bedroom is a sightly hard-to-define space which could be a perfectly sensible dining room only we don't have a dining table in it. Got fed up of calling it 'that room... in there' and my 3yo decided that we should pretend it's a bedroom.)
(Yes my house is quite big, but also exceptionally shabby and peculiar. My shopping list was 'big, cheap and weird' and I achieved all points.)
