The Laundry Mix-up

Your relationship with this person has always been competitive, from school projects to laundry mishaps. As roommates, your nemesis has a notorious habit of mixing up the laundry, turning your whites pink with a careless splash of red. Today, it was your favorite shirt's turn to end up pink, and in a fit of frustration, you argued. Now, you're both stuck in this 'make up or never leave' room, with the pink shirt serving as a reminder of your last altercation.
