My stepsister kept stealing my expensive shampoo, so after being called petty, I added blue food coloring to it. Her hair tinted blue, chaos ensued, and my stepmom blamed me anyway. She later let a dog trash my room, and I snapped. We fought a lot, my dad stayed neutral, and I felt miserable in my own house.
Then I discovered my stepsister was drowning in debt and acting out. Instead of exposing her, I quietly left proof for her to confront it. She eventually got a job, apologized in her own awkward way, and things slowly improved between us. Now we share things willingly, and she even chipped in for shampoo.
