THERE ARE SO MANY WAYS TO FALL IN LOVE—and so many people to fall in love with. When I was young, I went to a convent school, read historical romances, and dreamed of the day a modern Scarlet Pimpernel would sweep me off my feet, but really, I was only in love with my pony. As a result, in high school, I was way behind the girls who had already figured out the basics of human-to-human love and despaired of ever having a boyfriend. One of the reassuring things my mother said to me was that if you love someone, that person will love you back. Although there is not much evidence to support that theory, I decided to believe it, and eventually, like all mothers, she turned out to be right.

Now, as I watch my children fall in love, it brings back the memories of excitement, uncertainty, adventure, and the joy of belonging to someone. Falling in love means you aren’t a child anymore and, as Rumi writes in “Come to the Orchard in Spring,” nothing else matters. In these poems, John Keats captures the essence of desire, Percy Bysshe Shelley expresses the delights of kissing, and Christopher Marlowe rules out anything but love at first sight.

Throughout the ages, one of poetry’s challenges has been to express mystical experiences in language. Falling in love is a series of moments in which the ordinary becomes extraordinary. Those moments are not continuous, but the sense of union with another person is just about the best thing there is. Perhaps that is why Dorothy Parker celebrates our need to do it over and over again.
