Why things happen to me only?

I hear people saying the aforementioned question quite often.I feel like puking, when I hear that. I just want to shout "things don't happen to you, you come in the middle when things happen, arse!", but my convivial nature doesn't allow me to do so . I wonder what people will say if Bill Gates says the same thing. Some people may sleep and wake up with luck, some may not(it's purely coincidence).Life is unfair, we have to live with it. In fact, according to me luck is based on your perception. So, one should abstain from acting childish and change the way one perceives the world.
