This is my house!

Don't you just hate when people don't respect you or your home? OMG, I am steaming angry right now. My newphew came over tonight to watch a little cable and use my laptop computer since their pc is broken at the moment. My sister needs to use the laptop so I ask him to please let her use it since he has been on it at least 30 minutes. He tells me, "in a minute". Lets say a minute turned into another 30 minutes. I asked him again and again he responded with in a minute. I'VE HAD ENOUGH WITH THIS KID! He is a 7th grader who thinks he can do or say whatever the hell he wants since his mother doesn't discipline him. I'm already upset because earlier in the week he broke my acrylic album I'm working on and didn't even bother to tell me I found out on my own. I take the laptop from him to give to my sister and he gets all puffy about it. When they leave I'm trying to put on some movies/shows from my DVR and would you believe he deleted most of them? OMG I've had enough. I call his mother and YELL at her. I do the world for her kids and am not appreciated one bit. I am done being Ms Nice Guy with everyone that's it I've had enough. I will no longer hold my feelings in for anyone!
