I mean, I've had dealers who I got closer with after seeing them for so long, who would say once in a while.. "Maybe you should chill out a bit, man", shit like that.. but they always kept taking my money. Hah.
They know what dependence is, any more than that would be almost cruel. If they'll go out of their way to even say that they're better than most. But they always get a conscience too late. The girl who started selling me pain pills flaked on me for a similar reason, plus I had money to buy her whole stash, haha.
