I’m Rachel, 32, the “responsible one” in my family—always saving, working hard, and carrying the load. Earlier this year, I finally bought myself a cherry-red car I named Rosie, my first real gift to myself after years of sacrifice. But responsibility in my family often clashes with recklessness, especially with my younger sister Melissa, 28—impulsive, careless, and far from my opposite. The only reason I soften toward her is Lily, her five-year-old daughter and my beloved niece, whom I adore like my own. Melissa knows this—and she takes advantage of it.
