I Spilled My Little Sister's Paint Set on Purpose

So yeah, I'll admit it. Last weekend when my sister was busy with her art class and asked me to look after her paint set for a few minutes? I poured the whole thing out onto the floor of her room just because she got one of my favorite video games stuck in her PS4 months ago. I felt bad doing it, but I also kinda enjoyed watching all those pretty colors mix into one big mess. She was devastated, and Mom gave me a lecture about responsibility and taking care of others' things. But honestly? The sight of that rainbow puddle on the floor kind of made my day.
