I think Meg said it best:

It was like something out of a Gabriel Garcia Marquez novel–we fell in love when the butterflies were mating. I drove home between fields of corn, and hundreds of yellow butterflies chased one another across the road. The setting was idyllic, the relationship proved less so. He was an entrepreneur without a lot of extra time for romance, I was too young to be thinking about happily ever after. A year later, I was upset, and disappointed, and ready to call it quits. Driving home one night, I realized the butterflies were mating again. I smiled and watched two of them dance around each other. Then they hit my windshield.
