Strange how it works... Goes a little like this how you play: You date a few girls, and choose which one you like best. You start going steady after a while. Later she finds you are cheating on her with about five other girls, and she kills you and jacks your cash.
You may have noticed that everything runs in a pattern. When a new one comes in, the pattern may change slightly, but if you can figure out the pattern then it is pretty easy.
