How not to be mom's favorite:
Step One: Be born almost a full month late. Bonus points for waiting until the highways are all but impassible from winter storms if your family lives in a town without a hospital.
Step Two: Develop a penchant for disrobing publicly.
Step Three: Use new-found powers of speech to inform any and all friends and relatives trying to feed you that their food is "disgusting".
Step Four: Demand constantly, for a full year, that the family move into a camping trailer permanently.
Step Five: Throw a tantrum about being taken to kindergarten.
Step Six: Throw a tantrum about being taken home from kindergarten.
Step Seven: Paint the cat. Not a picture of the cat. The cat.
Step Eight: Paint the dog. With Cheez-whiz.
Step Nine: Sell all of your toys. And most of your brother's.
Step Ten: Be the only girl in the whole school clever enough to find pictures of naked people in school library books, and distribute widely with lascivious intent.
Step Eleven: Repeat step ten after being transferred to a christian school.
Step Twelve: Demand a trumpet. Play it enthusiastically and often. Never learn any actual songs.
Step Thirteen: Develop large breasts early and a willingness to wear a bra late.
Step Fourteen: Demand all of the privileges of young adulthood. Accept none of the responsibilities.
Step Fifteen, and this is crucial: Have a sibling that does none of the above.
