They have been together for so many years that they are no longer like two people but one strange four-legged creature. For her, so much of their marriage is about talk: she likes to talk, he likes to listen. Without him, she has no one to whom she can address her remarks, her observations, her running commentary about life in general.
An English teacher at school once said to her, 'Alice, one thing I hope you never find out is that a broken heart hurts physically.' Nothing she has ever experienced has prepared her for the pain of this. Most of the time her heart feels as though it's waterlogged and her ribcage, her arms, her back, her temples, her legs all ache in a dull, persistent way: but at times like this the incredulity and the appalling irreversibility of what has happened cripple her with a pain so bad she often doesn't speak for days.
