You know that feeling when someone treats you like dirt for years, then suddenly acts nice? That should’ve been my first red flag when my husband’s sister, Rachel, invited me to her son’s birthday. But it turned out to be a trap.

I’m Lydia, married three years to Alan, who loves me, but Rachel acts like I’m a stray cat. She’s always looked down on me for being a waitress and art student — “unworthy” of her brother.So when she called, all sweet, inviting me to Ashton’s eighth birthday, I almost believed she’d changed. But at the party, she handed me a surprise: “Face painting starts at 1:30. The kids would love it! You can buy supplies yourself.”She wanted me to work the party—for free.I swallowed my anger for Ashton’s sake and agreed. I bought the supplies, set up, and soon the kids and parents were loving my work. Rachel soaked up the praise, acting like she’d hired me.

Then, it was her turn. She asked for “something elegant” for her Instagram. I painted her face like a clown—white base, red nose, blue triangles, a huge smile, and glitter everywhere.Her shocked screams filled the room as everyone snapped photos. “Get this off!” she yelled, trying to wipe the glitter but only making it worse.

I packed up calmly, handed Ashton his gift, and whispered to Rachel, “Next time you try to humiliate someone, remember I’ve got more talent in my pinky than you have in your whole body.”Alan was stunned as we left. “I can’t believe she set you up.”“I can. And honestly, I’m grateful. Now she knows exactly who I am—a woman who doesn’t take crap lying down.”As we drove off, Rachel stood covered in glitter, screaming, while the neighborhood buzzed with gossip. Sometimes, the best revenge is just showing your true colors.
