Why to NOT have Siblings

I just got Metro Last Light, it's installing. I'm working on my Minecraft server. My sister wants to enter some stupid sweepstakes from Disney, so I'm doing it. She holds on to the stupid desk, then my brother pulls on to her leg. It stats tipping over the desk, falling down to the case, APU, Cooler, etc. So I yell at my sister to let go of the desk, she doesn't, so I push her away, the desk hits my $510 16 Gb, strongest APU in April 2013, the cooler, etc. But quickly gets up. My parents come up, of course yelling at me, then go back downstairs. I'm the only one in the playroom, starting up Metro Last Light as it had literally JUST finished downloading/installing. I then go over to the window, and see that either one of the 2 computers are smoking. I panic, thinking it might be on fires, and yell "FIRE!". I quickly turn off the PCs, and my parents come upstairs. We look at my computer, and the wires from the power supply are melted.
