"I fell in love. It felt exactly like a fall, a head-over-heels tumble into a state of unbearable lightness. The earth tilted on its axis. I did not believe in romantic love at the time, thinking it a human construct, an invention of fourteenth century Italian poets. I was as unprepared for love as I had been for goodness and beauty. Suddenly, my heart seemed swollen, too large for my chest."
