Sure, it STARTS with just little. "Just this once," you say to yourself, "just until this horrible growth on my toe is gone."
You score a little, maybe from a friend, maybe you go to the rough side of town, but somehow, you get it.
That cool jet of intoxicating liquid pours over your skin, and you're HOOKED!
Just a little more you say, just one more time. Then you start selling pc parts, first its a stick of memory, you can do just fine with 2 gigs you say, I'll be alright. But it is never enough. Never.
