The way I see it is this: I can want whatever the fuck I want. Most likely it's the same as what you want, though there's always a chance that it's not. If it is, we might want to work together (if we both want to) up to the point where we don't any more. If not, we should go our separate ways. However, if I want to hurt, or harm, or own you in any way, you should want to do something about it. Simple as.
