Jumping onto a cloud of faith.

My half malay half chinese cousin is really getting out of hands! He came over to my place and stayed for almost every single day of the end-of-yr holidays. That's fine when you have an adorable cousin who is obedient and respect whoever they should. But in my case, I've got one who keeps eating up all those tibits in my house even when I told him not to finish a particular one...Then there's him showing disrespect to my grandparents who live with me. He always say those offensive words as if he's the owner of the house. In addition, he always say some kind of disgusting words like, "Sexy bra", "You got hair down there?"
He's totally outta control.
I'd rather spend my time on playing my games or reading a book than listen to his bullshit...Plus I'm going to isolate him-dun talk to him, dun let his eyes comes into contact with mine.
Afew days back I took a afternoon nap after I kept my ps2 cable wire on top of my wardrobe to prevent him from playing behind my back.I told him not to play though.In the end he still played and it makes me mad! @#$%
Then yesterday midnight I kept the AV cable in another place but he still somehow found it and played my ps2 all the while in the morning before I woke up.That night he hit my "balls" with a solid thread ball and immediately after that he said he was passing me the ball. What the hEll? I declared that he cannot get his hands on my ps2 again ever but look what happened in the next morning? Served him right to get 160pts for his psle. GrrR....
