" Adrian's fragment also refers to the question of responsibility: whether there's a chain of it, or whether we draw the concept more narrowly. I'm all for drawing it narrowly. Sorry, no, you can't blame your dead parents, or having brothers and sisters, or not having them, or your genes, or society, or whatever - not in normal circumstances. Start with the notion that yours is the sole responsibility unless there's powerful evidence to the contrary. "

― Julian Barnes , The Sense of an Ending
