Why is it always your favourite items you ruin or lose?

It has always been a family joke that when my father buys electrical equipment for the rest of the family that I am the only one he takes out the extra warranties/guarantees/insurance for. A joke this may be but it is the truth. I must be the most destructive person on the planet. I have destroyed in a bundance laptops, cameras, stereos and even had the unfortunate incident of my car blowing up on a motorway. Yep, my luck isn't so great. And not to mention losing precious items like beautiful diamond earrings, prada leather gloves, gucci shoes, all sorts. Honestly, if it has any financial or sentimental value do not give it to me as it is guaranteed to implode or just simply disappear. Maybe it is a curse that some Wicca woman gave me in passing when i dropped my ice cream on their shoes when I was younger. Maybe it is just something that naturally has occoured in my gene pool. Who knows. But to me, right now, it is getting out of hand. It is spreading to other parts of my life and it isn't just physical/inanimate objects. Why can't someone just order me about and tell me how to look after myself, be responsible and grown up??!! That would help as I obviously can barely look after myself. Maybe I need to be tied up so I do not bore any children that may have the same nightmares?
