Beware of karma, Des.
I like to think that life is an equation that must be balanced. If something bad happens to you, the universe will pay you back with something equally good, and vice versa.
So, unless you go out of your way and do something exceedingly good (which I suspect violates the oath you took with Satan or something), the universe will come around and screw you.
If I were you, I'd avoid going out when it rains, and start to wear a cup.
