In David Foster Wallace's Infinite Jest, mother Avril Incandenza is remarkably devoted to her houseplants, so much so that she calls them her "green babies." Does one of your characters have a green thumb? Or does she dislike being responsible for houseplants? Think about what this might reveal in terms of the character's personality. What drives someone to take something meant to live outside and bring it inside? Is it a desire to cultivate beauty in her life, or does she prefer a more controlled environment to the wilds of nature?
