Believe it or not your exact argument almost word for word came up today in work, so you are not alone thinking it!
Must of cropped up everywhere, because we discussed the same old thing too! Going billions of miles and miles off topic, I actually thought the same thing about Jade Goody. A bit of bad press and she gets hounded on a day to day basis so much so that life becomes unbearable. The only way out is to get out of the public eye, which when you have the press following your every shadow about around the world is pretty hard to do! Therefore a lot of good media whoring and a lot of money later and then wham, out of the public eye for good! Everything thereafter is a conspiracy, because why would anyone bat an eyelid if she walked down the street?! I know I wouldn't, I would most likely be thinking "uh, she looks a bit like Jade Goody"!
I'd love to believe the same for Michael Jackson and that he's still alive in some normal sized house and having the last laugh at us all right now. But then reality kicks in, and I can't believe any conspiracy theory is true. Or can I?
