“ The expression in her eyes was bitter as nightshade. 'You ask me about regret? Let me tell you a few things about regret, my darling. There is no end to it. You cannot find the beginning of the chain that brought us from there to here. Should you regret the whole chain, and the air between, or each link separately, as if you could uncouple them? Do you regret the beginning which ended so badly, or just the ending itself? I've given more thought to this question than you can begin to imagine. ”
