Sarah replied in four seconds. With a laughing emoji.

I looked at the way the blue light from the TV traced the curve of her jaw.

She taught me that love isn’t just about finding the person who makes your heart race. It’s about recognizing the people who teach you how to love in the first place. And sometimes, those people arrive in the strangest packaging—a blended family, a shared fridge, a sarcastic stepsister who steals your phone and changes your life.

“More than you, clearly,” she said, snatching my phone. She deleted my message and typed something else. My heart stopped. She handed it back. The message now read: “I saw you listening to The Smiths earlier. Bold choice for a Tuesday. Tell me you’re not that melancholy in real life.”

For the first six months, we communicated through grunts and passive-aggressive sticky notes on the fridge. But then, one rainy Tuesday, she caught me rehearsing a text message to a girl named Sarah. I was on the couch, muttering to myself, deleting and retyping the same three words: Hey, what’s up?

But I never forgot the lesson my stepsister taught me, the one that went beyond dating tips and romantic storylines.

I bristled. “What do you know?”
