If you have it and you know you have it, then you have it. If you have it and don't know you have it, you don't have it. If you don't have it but you think you have it, then you have it.
The process is very gradual, you see. At first there's the tainted stage; they know what will eventually happen to them if they go on but they say, 'Oh God, don't do it to me do it again, please, please.'
