When I was around seven or eight years old, my mom's boyfriend, who we lived with, was throwing a house party. One of the guests brought along his 10-year-old son, Sherrick, thinking that I'd enjoy playing with them.
The kid was a little demon. Not only did he get his parents to let him drag along his Rock Band setup (drums, microphone, two guitars, the works.) but he decided on setting it up in my room. I just wanted to watch Toonami and do homework, but no, I couldn't. I'm already pretty annoyed at this point because I couldn't watch TV or use the computer, but then he gets bored of Rock Band and decides that it'd be really fun to start throwing my stuff around. Toys, knick-knacks, etc. The straw that broke the camel's back is when he asked me if he could pretend my video game discs were ninja stars. I told him no. And then he threw my copy of Spyro: A Hero's Tail right at me. I told his dad and he responded with a "So?". That REALLY pissed me off, so I went back to my room and slapped the kid a few times. Fast forward a couple minutes and I'm being humiliated in front of the entire house party because some stuffty brat decided he was Naruto and Spyro was his shuriken.
I've got plenty more stories to tell if anyone wants to hear 'em
