Murphy's Law

I was reading GinaRobbo: Why oh Why? It's remind me to read the Murphy's Law again. There are two reasons I like this Law.
1. Maybe it sounds silly I only like the pronounce of this word and the Chinese words of Murphy.
2. It seems solves many prombles about life.You can used the Murphy's Law to take yourself easier.Unlucky moments and unsolved prombles are not only in your life but also in everyone's life.
So I have the same question with GinaRobbo.Why haven't I won the lottery yet?
And my mother's questions is when my daughter can meet her Mrs Right?As we know here's coming a bus will never be the bus we wait for.
