The cold came to us like a thief in the night. You didn't notice it at first: it would creep in through the windows, under the doors, sneaking through gaps in the masonry. It would steal away what little warmth you still had. It would slide its icy fingers into pockets and up sleeves, taking and taking, until you realised all the heat you'd been saving had been snatched from you. No matter what defences we put up, it would always find a way to sneak in.
