" Was I wilfully blind when I married Michael? Of course I was. I knew about his heart condition - everyone did. But I fell in love with him and decided it didn't matter. We were going to live for ever, somehow. Now I know that the fact that we had the same initials, were both expatriates, had gone to the same university, and were of medium build made the relationship highly determined. But I might have done the research and discovered his short life expectancy or talked to psychologists about the pain of grieving or read books about the sadness of widowhood. But I didn't do any of those things. I looked away from those sad certainties and pretended that they weren't there.
Love is blind, not, as in mythology, because Cupid's arrows are random but because, once struck by them, we are left blind. When we love someone, we see them as smarter, wittier, prettier, stronger than anyone else sees them. "
