" Love, she reflected bitterly, wasn't something you bargained with or negotiated with...it lived by its own rules. Love appeared when you didn't want it and refused to go. It was like an invasive species that entered your garden without warning, and proceeded to grow wildly out of control, resistant to every method employed to kill it.
Basically, love was pigweed. "
