I have a little brother that loves to sit and play The Sims 2 on my Mac, problem is while he does it he drinks from a cup with a straw and for what ever reason or another he gets specs of soda/milk/water what ever he happens to be drinking on my 30" LCD. Is there ANY way of dealing with this I've tried yelling at him, a smack upside his head. Seems like nothing stops him he comes in when I'm at work and I come home to see spots of something on the lcd and even on occasion noticed actual runs down the LCD portion of the monitor what looks like into the frame, I have to clean it up and while I don’t mind doing it its really starting to annoy me. The LCD runs great but he's 12 almost 13 and nothing I do seems to make him change his ways, if I yell at him or hit him he seems to just take the soda down stairs and either drinks it there or just sits with it for awhile then when I'm gone he's sitting at the computer which is when I tell him to get off. I'm tempted to put in a doorknob that has a key to it (the one we have now doesn’t) or a dead bolt and just dead bolt the door with my father and I having the key. Is there ANY way to deal with this? Like I've said I've yelled at him and smacked him upside his head and still he keeps on doing it, even my parents yelling at him doesn’t seem to change his ways. DRIVES ME CRAZY!!!!!!!!!
