I am not entirely sure where or how you made the mental leap from old state school desks and metal chairs being high value mid century furniture, to (I think?) accusing me of having grey sofas and therefore apparently no right to speak on the matter?
As it happens, my house is more like Oz than Kansas, but thanks anyway for bestowing your magnificent and gracious all-knowing design wisdom on me. I am now suitably chastised and shall never dare comment on anything where you aren't around to correct my thoughts.
